Functionally, the Meltagun has more in common with a Plasma Gun than a Flamer. While the Flamer is used to incinerate large numbers of foes at short range, the Meltagun is used to attack point targets, destroying heavily armoured vehicles at short range by literally heating the vehicle's armour into slag and melting through to vulnerable internal components. Meltaguns work by firing a blast of pure fusion-based heat energy that can vaporise most organic troops, and even melt Adamantium. Melta Weapons are often carried by tank-hunting squads and are used as a special weapon by other squads.
