These special squads of [[Hardened Veteran]]s are not so much a formal unit type as they are the result of attrition. Often the only survivors of their parent company or even regiment, they are usually attached to other, newly-formed, regiments in order to pass on their hard-won skills to the new recruits. They are given greater freedom of operation than other squads and access to a wider array of equipment as well, along with whatever they can loot from the battlefield or otherwise "borrow" from other friendly units.{{Fn|1d}} Compared to normal infantry squads they tend to carry a greater number of squad support weapon including [[grenade launcher]]s, [[flamer]]s, [[sniper rifle]]s, [[plasma gun]]s, [[meltagun]]s and even a [[Heavy Flamer]]. Some are organised as [[grenadier]]s and wear [[carapace armour]] for additional protection, while others operate as forward sentries and equip themselves with [[camo-cloak]]s and snare mines. Still others specialise in demolition and carry a disturbing amount of explosives in the form of [[melta bomb]]s and [[demolition charge]]s.{{Fn|1e}}
