A Pre-Heresy Emperor's Children Legion Tactical Squad in combat.

A Legion Tactical Squad was a tactical formation of the ancient Space Marine Legions used during the Great Crusade and Horus Heresy eras in the late 30th and early 31st Millennia.

These squads were the mainstay of the Legiones Astartes and the force by which the Great Crusade reconquered much of the galaxy for the Imperium of Man and its Emperor.


The Legion Tactical Squad was the precursor of the present Adeptus Astartes Tactical Squads still utilised in the 41st Millennium.

The Warmaster Horus remarked on several occasions that there were few challenges of war that could not be met by, or did not require, the use of such units. One of these squads was typically composed of 10 Legionaries total, consisting of 9 Legionaries and 1 Legion Tactical Sergeant.

But some of these squads could contain as many as 20 Legionaries. It was by the fighting power of thousands of transhuman warriors such as these, armed and armoured for battle in the harshest of environments and the deadliest war zones, that the enemies of Mankind were crushed time and again.

One of the Space Marine Legion's greatest assets in open battle was the massed, coordinated hail of Bolter fire its Legion Tactical Squads could unleash.

Such was the firepower of this storm of explosive shells that enemy infantry formations and even squadrons of light vehicles would be blasted to the four winds in a single thunderous volley of bolt shells.

The Legion Tactical Squad was a highly flexible infantry unit, able to attack or defend at will, assault heavily fortified positions and take and hold strategic objectives or simply slaughter an enemy comprehensively in almost any terrain or situation.
