C-4
From SGCommand
C-4 is a powerful high-velocity plastic explosive created by the Tau'ri.
[edit] Overview
They are usually contained in block form, though the plastic itself can be molded into other shapes. (ATL: "Quarantine") The explosive is usually detonated if a detonator is placed into the C-4 and remotely activated, or placed on a timer. The destructive power of properly placed C-4 has proven very effective in fighting the enemies the Tau'ri has faced. Placing the blocks in key areas can destroy a Goa'uld Ha'tak vessel and even Wraith Hive ships, as well as blow open doors and destroy other key enemy targets. However, they are ineffective against Kull warrior armour and are somewhat ineffective to Tau'ri blast doors unless used with a second pack. C-4 is also used in Claymore mines.

[edit] History
The explosive is commonly issued to members of both the SG teams and the Atlantis Expedition. The Genii has a great interest in acquiring C-4 to incorporate into their own weapons. During the Battle of Atlantis, the Expedition were able to trade C-4 with their experimental nuclear weapons. SG-1 also destroyed two Ha'tak's by planting C-4 all over one and bringing that ship close enough to the other that the explosion destroyed both.
