Sentinels

When operating as autonomous units, the pilots of Sentinel squadrons are often forced to use their own initiative -- a quality that is not generally fostered in Imperial soldiers. As a result, many Sentinel pilots have acquired a reputation as would-be hotshots, glory seekers or insubordinate mavericks.

Some Sentinels, appropriately called Armoured Sentinels, may possess better cockpit armour-plating than the norm and are fitted with stabilisers to let them carry heavier weaponry. This transforms the Sentinel's role in an Imperial Guard regiment from one of armed reconnaissance and light infantry fire support to one of full-on anti-armour or even artillery support.

The Sentinel is a one-man, all-terrain, lightweight, bipedal combat walker that is used by the various regiments of the Astra Militarum. The Sentinel is most favoured when Imperial Guard patrols must move across rough terrain that would completely immobilise heavier vehicles.
