In Steel Beasts Professional supply vehicles provide ammunition or fuel resupply services to the armed vehicles, infantry squads, and missile/MG teams represented in the simulation. Such vehicles may be made available to Blue, Red, and other factional forces and will only resupply units of its own side. Thus a Blue supply vehicle cannot be used by another factions armed vehicles, regardless of enemy/neutral/allied status. Resupply of ammunition or fuel can be accomplished by moving the unit which requires resupply close to the vehicle (75m) and then waiting. Resupply will automatically commence within a couple of minutes. Note that full resupply may take some time.
