The C-4 charge

The C-4 is a common variety of the plastic explosive known as Composition C, which has been introduced in mid-20th centry.

Sergeant "Mech" from the Roughnecks A-01 team usually carried C-4 with him and used the charge in many occasions.

During the Battle of Fort Casey, Mech was ordered to place C-4 charges by Lieutenant Daugherty. The charges were time bombs and detonated after the Mobile Infantry left the Fort Casey.

Later onboard the Arachnid-controlled John A. Warden, when Mech, Ratzass, Major Varro, and Bugspray were heading to the Queen's chamber, Major Varro ordered Mech to place the rest of C-4 charges in the engine room, which later destroyed the ship along with the Arachnid force.
