Tank Fire Control System - New in ACE
M1A1 FCS ready for lasing
A number of armored vehicles (mainly tanks and IFVs) are fitted with a fire control system, comprising laser rangefinder, ballistic computer and turret movement sensors. FCS performs the following tasks:
Lasing for distance and automatically setting needed gun elevation for the current range.
Calculating and automatically applying lateral correction (lead) when engaging a moving target.
Compensating for vehicle's own movement.
Powering the system up
To initiate the fire control system, press the Lase key (default Tab). The system will boot up, and you'll see '0000' on the digital range display at the bottom of your screen.
To the left of the four digits there is a 'Ready' indicator. When it's visible, the laser rangefinder is ready for use. After each lasing, the indicator will disappear for the time needed for the laser to cool down, and reappear once it's ready again.
Engaging a static target
Place the crosshair over the target and press the Lase key. Range will be shown on the display, and the armament will be set for the needed elevation.
Shoot.
Note that elevation for given range is calculated for both main gun and the coaxial machinegun. It is also calculated for each kind of ammo. This means you don't have to re-lase when you switch to another weapon or change the ammo type - the needed elevation will be applied automatically.
Engaging a moving target
Smoothly track the target with the crosshair for at least 1.5 seconds, and press the Lase key. Range will be shown on the display, and the armament will be set for the needed elevation and lead.
Maintain the crosshair on the target and shoot.
The lead correction will be cancelled ('dumped') automatically once you stop moving the turret or start moving it in the opposite direction. You can also use the Dump action or key (default K) to cancel lead.
Switching to Battle Sight mode
Battle sight mode is used when targets are likely to appear suddenly at close to medium ranges and there might be no time for proper lasing procedures. In this mode the armament is set to the battle sight range, ensuring the maximum first hit probability in such conditions.
To switch to Battle Sight mode, select the BSGT action or press the Battlesight key (default B).
Lasing limitations
If you lase a target that is beyond the rangefinder limits (too close or too far), the display will show flashing '0000'. Armament will be set to the minimum or maximum range accordingly.
If the target is within the rangefinder limits, but beyond the maximum range of currently selected weapon, the display will flash. The weapon will be automatically set for its maximum range.
Vehicle commander rangefinder
Commander can lase for distance in much the same way the gunner does. To initiate the LRF, press the Lase key. To lase, press the Lase key.
Switching the system off
When the FCS is not needed, you can turn it off by selecting 'FCS OFF' in action menu.
