Deuterium-eight charge

D-8 charges are unstable deuterium-eight demolition devices that are used by Reapers against heavily armored targets, usually structures. The mines inflict significant damage to buildings.

After being tossed by a Reaper, the charges will detonate after a short delay, causing a large explosion that is most damaging against buildings, although utilizing such explosives is "an acquired skill that few troopers live long enough to master".
