The Aegis Defence Line is a length of prefabricated Imperial barricade — the dug-in firing position a Cadian line forms up behind, hauled into place and bolted down before the enemy comes. A fighter in base contact with or directly behind the line gains +1 to its cover save while it remains stationary, and counts as being in partial cover even against attacks that would otherwise ignore it. A Company Commander behind the line extends his command range by 3", the position steadying his whole net. A gang that controls the Aegis line as a territory may deploy it for free in one hold-the-line scenario each campaign.

The Munitorum Depot is a fortified supply cache — arms, ammunition, and the requisition-writs that keep a Regiment fed, walled in against raiders. A gang that controls the Depot as a territory draws a modest, capped sum of credits at each muster in the post-battle sequence, and once per campaign may requisition a single free special or heavy weapon from its stores. The income is drawn once at muster and does not compound; the Depot feeds the line steadily, not richly.
