actical Squads are the mainstay of the Space Marine Legions, highly versatile infantry units that can attack or defend at will, assault heavily fortified positions, and take and hold strategic objectives – or simply slaughter the enemy – in almost any terrain or situation. All 18 Legions make heavy use of Tactical Squads in different ways – it is by the fighting power of thousands of superhuman warriors such as these, armed with deadly bolters and armoured for battle in the harshest of war zones, that the Imperium has beat a bloody path across the galaxy at the head of the Great Crusade.
