Antimatter charge
From Halopedia, the Halo wiki
Template:Explosives List Anti-Matter Charges are explosive weapons used by the Covenant. They use anti-matter charges in a variety of ways. To blow through ship armor during boarding action, or as anti-vehicle and anti-personnel weapons. These appear to be the choice explosive of Ranger Elite teams, as they have sometimes been used to destroy Magnetic Accelerator Cannons on board ships.
Anti-matter is extremely unstable, any contact between unstablized anti-matter and normal matter causes an instant, massive explosion of energy.
A larger version of these charges, called Anti-Matter Bombs, are also used by the Covenant to destroy large objectives, such as stations or orbitals.
