The Astra Militarum is the largest cohesive fighting force in the galaxy. Fed by a constant tithe of soldiers raised from hundreds of thousand of worlds, its regiments form the vast bulk of Humanity's martial power. On countless worlds, the mortal soldiers of the Astra Militarum march in their billions to war, lasguns and bayonets readied to face any foe.
Batteries of heavy artillery fling innumerable tons of ordnance at the oncoming enemy, spearheads of heavily armoured tanks grind forward unstoppably, cannons roaring, cavalry squadrons mount swift counter-charges on the flanks, while squads of elite operatives descend from gunships on missions of vital importance. Meanwhile, officers add their shouted orders to the great cacophony of war, exhorting their troops to fight all the harder. Wielded with the appropriate will, the Astra Militarum will pulverise whatever stands between them and victory.
