The M978 HEMTT fueler is the heavy 8x8 tanker counterpart to the M977 HEMTT cargo truck. It is equipped with a 9500 liter (2500 gal) tank, and can refuel two vehicles simultaneously.
In Steel Beasts Professional, this vehicle may be made available to Blue, Red, and other factional forces. The HEMTT Fuel vehicle will only resupply units of its own side. Thus a Blue HEMTT Fueler truck cannot be used by another factions armed vehicles, regardless of enemy/neutral/allied status.
Resupply of fuel can be accomplished by moving the unit which requires resupply close to the vehicle and then waiting. Resupply will automatically commence within a couple of minutes. Note that full resupply may take some time.
Beginning with revision 4.156 the HEMTT Fuel vehicle is crew-able at the Commander's (F7) and Driver's (F9) positions. Though normally unarmed, this vehicle may optionally be equipped with a ring mounted .50cal M2HB machine gun at the Commander's position. Additionally, the vehicle may be outfitted with improvised armor kits to enhance crew survivability.
