Smoke is effective only against laser IR or visual guided missiles Multi spectrum screen is effective against laser IR visual or radar guided missiles In comparing the actual size speed and filler weight warhead size to the TOW 2 average in general most systems do better against larger and slower targets In particular the systems that send out a shower of shrapnel or ball bearings rockets and canister are given more opportunity against these targets than those with single projectiles warheads Smoke types are once again heavily penalized against very fast moving targets Secondary effects may also be caused by the action of a PMD system Shrapnel from rockets and canister will affect unprotected troops and other soft targets within their radius of action 85 meters for canister 15 meters for rockets Likewise if the incoming missile detonates it may create additional damage within a radius based on its filler weight from the point it is determined to have detonated Deflected missiles can also produce casualties either by hitting another target in the same location or less likely another location along the flight path The simulation takes all of these factors into consideration and calculates the damage accordingly 3 5 3 PMD Ammunition Depletion One special topic concerns the way in which PMD ammunition depletion affects the efficiency of the system In some cases this will be straightforward as

4. 3 2 7 4 Target Size Targets sizes are determined from the perspective of the unit or missile viewing them and reflect how big the object appears not necessarily how big it is in reality As such objects appear smaller as they get further away and a small object close by may look larger and be easier to hit than a much larger target at a greater range Target sizes are measured in square arc seconds There are 3600 arc seconds in a degree and for comparison the full moon measures approximately 1800 arc seconds across or 5650 square arc seconds in total size The size determination routine initially builds a representation of the target object out of blocks based on the target s length width and height values that are defined in the Data Tables If the target has a turret it is superimposed on the hull in a centered position and the facing set accordingly in relation to the hull The object is then rotated in 3 dimensions to match the perspective of the viewer and the silhouette values are applied to reduce the blocks to approximately the actual contours The actual dimensions are then adjusted for the range between the object and the viewer giving the nominal apparent size of each side and the total object in square arc seconds Apparent Size Orientation and LOS Effects Actual The 3 dimensional object is condensed to a 2 dimensional area in the observer s field of vision Simulation The apparent area of
5. Direct Fire DF otherwise it is known as Indirect Fire IF 3 2 1 Direct Fire DF Direct Fire is used when the firing unit can directly aim at its intended target As an example a rifleman aiming and firing at an enemy target uses DF Usually a unit using DF will be able to visually see its target However there are times when this will not be the case An example would be engaging a target several hundred meters away in a dense fog The target will not be visible to the naked eye but it could show up clearly with a thermal sight Thus the thermal sight allows the fire to be directly aimed and thus DF DF can be used against any target type including area point locations enemy units or weapons systems or objects such as buildings and obstacles It can also be used as area fire against a general location which may or may not contain other unknown targets DF can be used by all munition types powered or not guided or not or even physical or not e g energy weapons All Gun Launcher systems have the capability of using DF no specific data settings are required DF is resolved in four basic steps e The firing parameters are calculated and checked to be both physically possible and within the firing unit s limitations e The total number of rounds to be fired is determined and the rounds are fired one at a time e The round either impacts immediately as in the case of a tank main gun round or a temporary

However the path will not be determined in a regular fashion like the orbit but rather must be determined based on the conditions at the time the order is given including the aircraft s heading it s ultimate objective location and the heading it must have at the objective Essentially the Al acts as the pilot and will fly the aircraft as needed based on its capabilities and the current situation In determining the path to the target the Al checks to see if the aircraft can skew to the proper heading and fly straight in For this purpose the angle to the target must be less than 30 degrees If so the aircraft flies straight in and no other adjustments are necessary Otherwise the aircraft must maneuver to achieve the proper objective The Al will determine a set of turns and flight segments to achieve the objective Samples are shown in the illustration below Airstrike Maneuver Path Determinations Straight in vs Maneuver AI Controlled N N The aircraft s turn radius is based on its N r flight characteristics speed and weight P E anO L O T 30 i Te ii ra wa Case 1 Ifthe target is within 30 of the aircraft s heading it will fly straight in Case 2 Ifthe target is more than 30 from the aircraft s heading it will maneuver in through a series of turns with the first turn always away from the target ie The path includes the straight run in leg before

Otherwise the speed may be reduced based on the ratio of the actual grade to the maximum grade applied to the maximum weapons data speed e Acheck is made to see if the unit suffers any mechanical breakdowns and if so an immobile detachment is created e If the terrain is on fire the unit is checked for damage based on how long it had been contact with the fire how strong the fire was and the basic unit characteristics e If the unit is in contact with chemical agents the effects are assessed along with any automatic MOPP protective measures adjustments e If the unit moves into a location containing enemy units a check is made to determine if a close combat situation exists If so the unit will stop moving until the close combat situation is resolved or it suffers some adverse combat result Close combat was discussed previously in the manual e If the moving unit is in the same location as a minefield whether enemy or friendly known or unknown the computer will determine if it hits a mine and if so assess the results Mines are discussed in more detail below Disorganized units from airdrops with movement orders will not begin moving until they become organized Wavering units from morale effects may or may not move if they have orders to do so depending on their situation Units that must emplace before firing such as artillery will automatically be given orders to do so whenever they complete executing their existing m

The shorter the transmission times the less likely it is the enemy will home in on the source of the signal and the quicker the unit can begin executing those orders Leaders with high communication skill also reduce the internal friction of the unit and the time it takes to join units together e Targeting This leader value applies to how effective a unit will be at achieving optimum target selection by reducing target overlap Overlap is when one or more friendly weapons systems engage the same enemy target but the additional fire has little or no effect Leaders with a high rating in this area can better judge how effective their fire is and potentially assign fire to other targets accordingly e Competence This is how often the leader will mis interpret orders both movement and targeting In most cases even when the orders are misinterpreted the effects will be minor the speed may be a little off or an adjacent unit targeted However for very bad ratings 75 or less the leader may change the unit s movement objective or path or even decide not to move in which case the orders will have to be re issued Leaders with higher competence levels will also reduce the internal friction level of the unit e Initiative This is a measure of how effective the leader is at operating in the absence of orders While good and bad are relative in this case leaders with higher ratings are more likely to discern the force comm

22. 1 8 5 SITREP Messages Once an enemy unit or object has been detected in some way the information is disseminated to other units via SITREP reports These reports are first sent by the detecting unit up to its HQ unit which then disseminates the information of other units in the formation If the detecting unit is a HQ it will also disseminate the report to its subordinate units The transmission of SITREP s requires an amount of time determined by the force s communications levels adjusted for the sending and receiving units capabilities and conditions Additionally a unit is limited in the number of reports it can send concurrently based on its communications capabilities so it will take time for information to percolate back to you as the TF Commander and throughout the force If a unit is interrupted in the middle of sending a SITREP by enemy action or some loss of communications the message is also lost and will need to be started from scratch if the communications situation improves SITREP s are sent whenever a unit discovers new information be it a newly found enemy unit or an object or a combat report In some cases the unit receiving the SITREP will already know the information in which case the report is ignored However it is still sent nevertheless because the sending unit may not know the higher unit already has the information from another source Section 1 9 Play By Email PbeM Point of Attack 2 is design
23. 13 1 Fixed Wing vs Hover capable Aircraft The simulation makes a distinction between fixed wing aircraft which must maintain a certain minimum speed and hover capable aircraft that can reduce their speed to zero The determination is based on the data entered for the maximum road and cross country speeds in the Weapons System Data table Aircraft with a maximum cross country speed greater than zero are considered fixed wing and those with a value of zero are considered hover capable One point to note is that the term fixed wing is used in this context only for simplicity and in reality means any non hover capable aircraft Note Also for simplicity the database uses only two speed values maximum cross country speed and maximum road speed For aircraft the maximum road speed is the aircrafts actual maximum speed while the maximum cross country speed is actually the minimum speed Because fixed wing aircraft cannot reduce their speed to zero they must be constantly moving Any air unit without specific movement orders will be given orders by the computer In most cases the air unit will be ordered to orbit parallel to the front line at a depth based upon its current location However if the air unit is performing a mission of some type the computer will issue appropriate orders Hover capable aircraft are not under this restriction If they find themselves without movement orders they will simply stay in their current

26. ECCM Electronic Counter Counter Measures are used primarily in the routines dealing with radar guided missiles However they also determine the amount and accuracy of detection information ECM are signals produced by the target to confuse or disable the tracking radar ECCM are measures taken by the radar to eliminate the extraneous ECM signals produced by the target and usually consist of computerized signal filters and sophisticated digital analysis systems The target s ECM rating is determined by its Decoy System The radar ECCM rating is set as part of the radar s characteristic values Once an enemy object has been detected the computer checks if it has a decoy system that can produce ECM If it does the ECCM rating of the radar is subtracted from the ECM rating of the target If the value is equal to or less than zero the ECM has no effect Otherwise the amount is subtracted from the detection probability to arrive at the information level The higher the level the better the information gained by the contact Even at 100 though the exact weapons system model of the contact will never be specified only the type will be given i e Fighter Aircraft not US F 15E The same basic procedure is used to modify the hit probability of radar guided missiles The ECCM rating of the guidance radar is subtracted from the target s ECM and if the resulting value is greater than zero it is subtracted from the hit probability

Types of Minefields The simulation recognizes three general types of minefields Deliberate Hasty and Scattered Each type has slightly different properties and characteristics in the simulation Note these minefield types do not specifically correspond to the doctrinal procedures or nomenclature of any armed forces they are used only to help identify common minefield characteristics e Deliberate minefields are placed by hand according to a pattern and the location of each mine known and or recorded for reference These types of minefields are placed by hand and include defensive mines distributed around a perimeter as well as large barriers comprised of rows and clusters that stretch for several hundred meters or more Significant deliberate minefields are normally marked and the mines themselves buried and well camouflaged Hasty minefields are placed within a known and well defined area and at a specific mine density but the location of each individual mine is not usually known exactly or recorded The minefield boundary is usually marked depending on the situation and if time permits The most common example of this type of minefield is one placed by rapid mechanical means mine throwers The mines in hasty minefields are not buried but may be slightly camouflaged Scattered minefields are placed by remote means in areas not normally closely observed by friendly forces The exact area and placement of each mine is not known and the

Munitions that are destroyed as a result of guidance loss may be determined to detonate in their current location or at a location further along their flight path depending on the munition s current altitude speed and distance from the target When this occurs units and objects nearby are subject to normal combat losses from random impacts For example a guided bomb may lose guidance to its intended target but it will still hit and explode somewhere possibly even on its originally intended target 3 2 7 3 5 GPS Global Positioning System GPS is based upon a series of radio transmitting satellites in geo synchronous earth orbit Appropriate receivers on the earth s surface can detect these signals and use them to determine their location within a few meters This exact position information can also be useful for guided munitions as long as the position of the target is also known and it is relatively stationary In that case the guidance system of the munition can continually monitor its progress and make course corrections as necessary to arrive at the target location It also enables the munition to fly a predetermined flight path exactly without relying exclusively on less accurate dead reckoning methods While GPS can be used as a sole guidance source it is often used in conjunction with other guidance methods so that compensation can be made for moving targets or imprecise original target position information In these cases t

191. he munition detects the energy and aims for the center of the source The most common forms of energy used for homing are radar signals heat IR radio light and sound Homing munitions can often successfully tolerate interruptions in the energy source especially if the target is stationary or if the interruptions are short enough that the munition doesn t lose the target from its field of vision A prime example is a HARM missile that guides in on energy pulses emitted by enemy radar stations The station does not emit energy continuously but because it is stationary or slow moving the missile can home in on the last known pulse location with relatively good results The pulse rate for radar transmitters is set to a default value when a scenario starts but can be adjusted by the owning player for each radar unit in his force It is worth remembering however that the pulse rate setting is a balance between effectiveness and protection On the one hand a low pulse rate will protect the radar from HARM missiles but on the other it will also mean that the radar is less effective at detecting enemy aircraft Interruptions in energy emission detection have the greatest effects on accuracy when they happen as the munition nears the target although the simulation makes checks every second over the flight path and adjusts the accuracy accordingly The longer the interruption continues or the faster the target is moving across the munitio
