Changes

When the nascent Imperium reunited with the [[Knight Worlds]] during the [[Great Crusade]], they found that, in addition to the [[Knights]] used in battle by the nobility, there were also lesser unarmed frames used by [[Drover (Knight World)|Drovers]] – the non-noble herdsmen who tended the fields and estates. One such popular and tested frame, the [[Drover Walker|Drover suit]], would be armed and adapted into the Sentinel widely used by the [[Imperial Army]] and [[Imperial Guard]]. {{Fn|23}}

Besides the addition of more armour or different weaponry, Sentinels can be modified in a multitude of ways. The most common include adding [[Camo Netting]], a [[searchlight]], [[smoke launcher]]s, and/or a [[Hunter-Killer Missile]]. Other adaptations can be made depending on where the Sentinel operates, such as servo-driven claw spikes for a better grip when walking over glacial planes.{{Fn|4}}

The bipedal locomotion afforded by the Sentinel gives it a unique ability to advance into terrain that other armoured vehicles with tracks could not possibly hope to achieve. This allows it to stalk through dense jungles or urban ruins to locate and wipe out pockets of enemy resistance, though their light armour and exposed crew compartment leaves them vulnerable to even small-arms fire. Armoured Sentinels which have an enclosed cockpit and heavier weapons however are used more as roving hunter-killer units, seeking out and destroying enemy tanks where they can find them.{{Fn|4}}

'''Cadian Pattern Sentinels''' are produced on [[Cadia]] and typically mount a rapid-firing [[Autocannon]], making it ideal for destroying armoured infantry and light-to-medium vehicles. Like the Armageddon patterns they too are often given [[extra armour]] in order to better protect the pilot.{{Fn|3}}

The '''Catachan Pattern Sentinel''' originated on [[Catachan]] and is often employed by other regiments native to [[Death Worlds]]. Adapted towards the claustrophobic close-quarters common to jungle fighting, it is armed with a [[Heavy Flamer]] and carries a massive chainsaw cutting tool, useful not only for clearing brush but also the enemy as well.{{Fn|8}}

'''Tallarn Pattern Sentinels''' as used by [[Tallarn Desert Raiders]] and similar regiments is ideal for fighting over open desert terrain. It has wider based feet which allow it to spread its weight over a larger area, preventing it from sinking into the sand, and includes sand filters to prevent the power-plant from being clogged by fine particles. Its typical [[Multi-laser]] weapon system is ideal for fighting infantry and light vehicles.{{Fn|6}}

The '''Support Sentinel''' is a heavily-armed variation designed to provide immediate fire support, either as part of a Sentinel company or attached to infantry platoons. It is armed with a [[Multiple Rocket Pod#Support Sentinels|Multiple Rocket Pod]] for anti-infantry firepower, or a [[Multiple Rocket Pod#Support Sentinels|Missile Launcher]] capable of firing [[Multiple Rocket Pod#Imperial Munitions Types|Frag]] and [[Multiple Rocket Pod#Imperial Munitions Types|Krak]] missiles. It is also modified with additional range-finder and target acquisition gear, including a [[Targeter]] mounted on a telescopic periscope, allowing those armed with a Missile Launcher to fire at targets outside their line of sight. Additional modifications include an armoured screen to protect the pilot against missile jet-wash, and a Drop pattern variant which incorporates the Drop Sentinel's design features. Support Sentinels are uncommon, with each Sentinel company lucky to have one or two squadrons, so they are highly valued by their commanders.{{Fn|6}}

'''Sentinel Powerlifters''' are a rear-echelon variant used primarily for loading and unloading equipment and supplies. These Sentinels are equipped with large hydraulic claws, also known as a '''Powerlifter''', easily capable of crushing a man to death, along with a counterweight mounted on the rear to prevent it from tipping over. They are a common sight on airfields, space ship flight decks, and artillery positions, but will only be called upon to defend their position as a last desperate measure. {{Fn|5}}
