How the Battletrax combat system works
We have attempted to replicate as closely as possible the
prototypical commands and process followed by a WWII tank
The US Armored Force Field Manual of Tank Gunnery published in
April 1943 gives the following formal commands when engaging a
Indicates Target Type
Indicates to loader to use armor piercing ammo
Indicates position of target relative to barrel position
Continues traverse until gun aimed at target
Indicates estimated range in yards
The Battletrax radio system is independent of the RC system
controlling the model. Although both can be operated by one
player there is advantage (and increased enjoyment) if the
player driving the model takes on the role of Commander & Driver
and a crew member takes on the role of the Gunner operating the
Battletrax fire controller.
The Commander identifies the target to the Gunner, specifies the
ammunition to be loaded, estimates the range and orders "Fire!"
The player inputs the data into his Battletrax fire controller
and the virtual crew, via the unit sound chip, confirms the
range (or change in range) and the player presses the "Fire!"
button. The Battletrax fire controller operates the model's
Using information from the model based GPS the system compares
the Commander's range estimate to the actual range. Taking into
account the height of the target and the trajectory of the
firing gun the system declares a "Hit!" or "Miss!". The virtual
crew provides feedback to the Gunner as to whether the "Miss!"
is "Over!" or "Short!". The Gunner conveys this to the Commander
who can then "bracket" his fire by ordering a range adjustment
for the next shot e.g. "Up 200".
On obtaining a "Hit!" the system determines at what height and
where the shell hits the target. On board compass and turret
encoder provide the orientation of the target's hull and turret
independently. Therefore the system can identify the thickness
of the armour at the point of strike. The angle of strike is
calculated by combining the vertical slope of the armour with
the horizontal angle of attack. The US Army Armor Basis Curve is
applied to determine the effective armour thickness at this
Using historic gun performance data the system determines
whether the firing gun can defeat the armour. The virtual crew
will report "Target Destroyed!", or that the shot failed to
penetrate the armour. In the event the target is destroyed the
system automatically triggers the detonation of a stage
pyrotechnic in the target tank.
Appropriate sound effects for cannon fire, shell hits and a tank
brewing up supplement the virtual crew reports.
The system provides for over 100 types of tank and your model
can be programmed to represent any individual type you want e.g.
a King Tiger, StuG, T34, Sherman Firefly etc providing for over
10,000 different tank v tank permutations.
In addition a whole array of anti-tank guns are represented
