Reaver crews are the same as found in other Imperial Titans, consisting of a Princeps with overall command of the machine, two Moderati who control its weapons and movements, and a Tech-Priest to manage the plasma reactor, assisted by servitors wired directly into the Reaver's many systems. Reavers therefore are less suitable for extremely heavy fighting in cities and other built-up areas, though their speed on the open battlefield makes this problem less of an issue. This unique feature makes it much harder for an enemy to knock out the Titan when attacking from the front, while simultaneously making the reactor an easier target when attacking from the sides and rear.

The Reaver differs from other Titan designs in that it's plasma reactor is placed in the rear of the carapace housing.

In a one-on-one duel a Warlord can easily destroy a Reaver by itself, while a Plasma Destructor can drop a Reaver's void shields in three shots, with another three scalping its head and shredding its carapace. However the Reaver is not invulnerable, especially when fighting against larger Titans. Indeed such is the power of the Reaver that only another war engine of similar capability or entire tank battalions working together have a hope of defeating one in open combat. It can mount up to three weapon systems of terrible destructive power which are configured based on its mission role: those operating in support of conventional forces typically mount short-ranged, rapid-fire weapons and close-combat weapons, while operating as part of a Titan battle group one or two will be given longer-ranged firepower.

The Reaver boasts four Void Shield generators and is protected by thick, well-sloped layers of adamantium armour plating, giving it an immense level of protection.
