Fire Direction Centres coordinate the fire of several indirect fire systems (Tube Artillery, Rocket Artillery and Meson Guns) at a single target, convert correction requests from Forward Observers into precise elevation, traverse, propellant, and trajectory commands - and calculate the effects of a wide variety of factors on artillery accuracy (e.g. Atmospherics, elevation of firer and target, etc.). While Fire Direction Centres are not required to conduct indirect fire, they increase the effectiveness of that fire dramatically.
TL–15 FDCs have an effective range of about 80km. Beyond this range, the effectiveness of the FDC declines dramatically. note this is not related to the range of the artillery weapons themselves but to the distance from the FDC where that fire impacts its target.
The Imperial Marine Fire Direction Centre vehicle is designed to be externally similar to the standard Imperial class Grav APC (Marines) to enhance its battlefield survivability. For this reason, it retains a fully equipped Grav APC turret, although it does not carry the missile reloads of its APC cousin. This allows the vehicle a robust self-defence capability, and allows it to "service" small, nuisance targets in its own without having to waste a fire-mission. Retention of the missile fire control system also means that the FDC vehicle retains the 300km range laser-designator (although it is usually too valuable to designate its own targets).
Like the Norris class Grav Tank, this vehicle has dispensed with the airlock arrangement and instead has a 35m3 life-support module for its 6 crew. This makes it one of the few vehicles utilising the Imperial class Grav APC family hull that does not use the standard life-support system.
