Where a commanding officer stands, his Command Squad stands with him. Drawn from veteran Guardsmen and trusted specialists, the squad exists to amplify and enact a commander's decisions, forming the nerve centre through which his orders reach the wider force.
Each member serves a distinct purpose. A vox-caster operator maintains the vital links of communication and calls down support. A medic labours to keep both the officer and his soldiers on their feet and fighting. A standard bearer raises the regimental banner, a rallying point that stiffens the resolve of every trooper who can see it. Others carry special or heavy weapons, or simply stand as bodyguards between their commander and the enemy's guns.
On the battlefield the Command Squad functions as a node of command and control. From its position the officer issues the barked tactical directives that spur nearby squads to greater fire, faster advances or more stubborn defence. Precisely because a commander is so valuable, he is a prime target, and so the squad's foremost duty is grimly simple: to keep him alive and his orders flowing, even as the shells fall and the line buckles around them.
