The Seraphim T3 Support Armored Command Unit is a Seraphim unit. It is a command unit. The Seraphim sACU is by far the most powerful of all the races' support commanders and is the most powerful non-experimental land unit in the game. When upgraded with a Personal Shield Generator and a Nano-Repair System it is capable of soaking up over 100,000 damage with a regen rate of 250 HP/s, while its Overcharge system allows it to put out insane amounts of damage as long as you can afford the energy cost. Combined with the standard sACU traits of good speed, amphibious movement and a highly efficient T3 engineering suite, this makes the sACU one of the most powerful weapons in the Seraphim player's arsenal and in groups they're all but unstoppable.
