Melta bomb

A melta bomb is a type of explosive charge belonging to the melta design tree. Typical examples have dimensions analogous to that of a grenade, but can be larger. When activated, they explode with intense thermal energy, 'melting' the target away. Like all melta-weapons, melta bombs are especially useful for attacking vehicles, buildings and other armoured targets.¹
