C-4

C4 is a powerful plastic explosive created by the Tau'ri. The explosive was used several times by SG teams and the Atlantis Expedition.

The destructive power of the explosives has proven very effective to fight the enemies the Tau'ri has faced. Placing C4 in certain key areas can destroy a Goa'uld Ha'tak vessel. The explosive can also be used to blow open doors and destroy other key enemy targets.

The Genii has a great interest in acquiring C4 to incorporate into their own weapons.
