Does it have flippy arms?
Nope..it is on an Annhilator Chassis
How do you get around behind the Gausszilla anyway? It only takes 3 MP to pivot in place, and if he just parks, damage at range will overwhelm the smaller, faster machine long before it inflicts any meaningful damage anyway.
Terrain was such that if the Grand Dragon lost initiative, it could get behind cover, and there was nothing the GZ could do to get
LOS, and if he won, no matter how the GZ turned, he could get in the rear. Instead, the Grand Dragon pilot took to woods one turn while closing to medium range with his weapons, and then..went down the middle, not using terrain past that point..
