G-4

G-4 is a Colonial plastic explosive using an A-type detonator fuse as an electric ignition source.

Explosives

G-4 explosive is placed on a door in the New Caprica Detention Center

Sharon Valerii's Cylon persona planted five G-4 charges inside Galactica's water tanks, their detonation resulting in the loss of over 60% of the ship's water reserves (TRS: "Water").

On Galactica, G-4 explosives are located in small arms lockers, thus under the domain of the Master-at-Arms, who was Sergeant Hadrian at the time (TRS: "Litmus").

G-4 is also used by the human resistance movements on Caprica and New Caprica against Cylon occupations there ("Downloaded," "Occupation").

Detonator

The human-side of Sharon Valerii "discovers" a case of detonators, where half are removed (TRS: "Water").

A-type detonators are often, but not always, used as a fuse for G-4, and possibly other explosives. They can be time-delayed or manually triggered by a red button on top of the detonator.

Aboard Galactica A-type detonators are kept in cases. One such case, from which Valerii's Cylon persona purloined from the small arms locker during her sabotage efforts, features 12 A-type detonators with slots labeled A-1 through A-12 (TRS: "Water").

Notes

• G-4 is identical in function to the real-world Earth's C-4 explosive.
