Arbiter (StarCraft)

The Arbiter is a high cost support unit. It relies on fairly high shield and hit point strength to survive, rather than its low powered direct attack.

It has a passive cloaking field that cloaks all nearby friendly units, but not itself. A popular strategy is to attach Arbiters and observers to a carrier group. The carriers attack from under the cloak, and ward off attacks on the uncloaked Arbiters.

The Recall ability offers a powerful means of strategic movement. Arbiters may use Recall to teleport forces into an enemy base, circumventing any defenses.
