The Plasma Charge is a Covenant air-to-ground plasma weapon utilized by Seraphs for ground bombardment. They are initially focused pillars of superheated gas, but quickly lose integrity and billow out into destructive conflagrations that can overwhelm even SPARTAN-III battle armor, as seen in the tragic Battle of Pegasi Delta, where there was sustained usage of plasma charges which were sufficient to slaughter hundreds of the commandos of Beta Company in the open. Only finding cover saved the SPARTAN-IIIs from Seraph plasma charges.
These seem to be the Covenant equivalent of unguided bombs or rockets, used in a similar manner and functioning in a similar capacity.
