Mid-range Bolos (say, late model Mk XVs and up to the really gross Mk XXXI and later) have an advanced AI-directed prime weapon which was in effect a shaped thermonuclear explosion which sees pretty much the entire energy directed in a tight shot at the enemy. This weapon, encased in a fusion powered war hull made of advanced alloys backed by shields and energy-absorption grids designed to withstand pretty much anything short of a direct hit by a tac nuke. Laumer built them tough. ;-)
There's not much that can worry one short of their enemy equivalent.
