C-5

'C5' is a fictional version of the composition explosive C4, & it has only been used once in 24. C5 in an extremely powerful explosive, being that a few ounces were needed to take out a small sub-power station in Section 26GG of the Saugus power grid.

Andre Drazen sent one of his men to take out the power station with the explosive to knock out the power to the Class 3 Detention Facility where Victor Drazen was set to be delivered by helicopter. This mission resulted in the release of Victor Drazen, and the capture of Jack Bauer by Andre's men. Surprisingly, however, Andre decided to use a shaped C4 charge to blow a hole in a steel wall to enter the facility.
