The Bolter, also called a Boltgun, and its variants are some of the most powerful hand-held ballistic anti-personnel weaponry in use by the military forces of the Alliance of Nations (mostly the Imperium of Man) and the Imperialists. It is a powerful assault weapon that fires explosive kinetic rounds colloquially referred to as bolts. The Bolter is a weapon synonymous with the Adeptus Astartes, and rightly so. However, although the Space Marines are its primary users, the Bolter finds itself in use in military organisations throughout the Imperium. The weapon is fearsome, with explosive rounds capable of ripping through or blowing apart a foe. The Chaos Space Marines of the Forces of Chaos were issued their Legions' Bolters during the First War, and therefore, use generally older variants than the patterns available to present-day Loyalist Space Marines. The Bolter is a mid-range anti-personnel ballistic weapon that lies between the lighter Bolt Pistol and the more effective Heavy Bolter. The standard pattern Bolter can easily be wielded by a Space Marine, but smaller pattern Bolters must be used by the Battle-Sisters of the Adepta Sororitas.
