The RCB is a weapon that appears in the Commandos series as an explosive that can be detonated from a distance when it is needed. It can be picked up again and replaced unlike its counterpart, the time bomb that explodes in 20 seconds after placing. The RCB has the same explosive radius as the TB (Time Bomb) and can destroy any vehicle or certain fortification or structure such as Anti-Aircraft Guns and Fuel Tanks. The hotkey for the RCB in C2:MoC is "S". The RCB can only be used by the Sapper.
