The A.R.E.S. is massively powerful and is easily capable of destroying the nearby guards. It can be equipped with one of three weapons when the player activates it - anti-personal napalm, anti-armor missile pods, or all-purpose cannons. The anti-armor missiles are advised, as the siege tanks and vikings are more formidable than the Dominion's marines, and the player's current forces can kill them without the need for the warbot. On some higher difficulties a thor may be encountered in the area as well. The A.R.E.S. has a timed life and will self-destruct when it runs out regardless of health.
A feat of strength for the mission requires the player to kill the nearby brutalisk with the warbot on Normal difficulty. Due to the A.R.E.S.'s timed life, this requires the player to clear out the cargo bay on their own. Once this is done they can activate the A.R.E.S. and march it to the chamber with the brutalisk. Clearing out the cargo bay without the warbot is the only difficulty, in a straight-up fight the A.R.E.S. is more than a match for the brutalisk. Because the brutalisk is an armored unit, the anti-armor missiles armament is again advised.
Rory Swann is able to use the Combat Drop ability to summon four A.R.E.S. warbots to the field. The warbots have a timed life of 60 seconds and are fully controllable, and attack both ground and air units.
