When efficiently deployed, a squadron of AT-ATs can quickly take control of a wide area, making it easy for imperial forces to dominate a planet.
If Veers is at an exterior Hoth site, use 2 Force to search your Reserve Deck and take one AT-AT into your hand. OR If you have 3 AT-ATs at three different Hoth sites, your Force drains are +2 at Hoth locations this turn.
