Both of my units have the legs mounted as turrets so they are flexible to a degree at the \'hip\' joint though to mimic a normal hip it does not bend backwards. It allows for some aesthetic positioning; leaning, torso twist at the hips. The screen shot has a \'reverse-thrust\' pose Mayo, one with it\'s legs blown loose from a missile hit, the far one is splay-legged off-line with it\'s pilot shot out and the Catsup has the fourth squad member pinned prone under it\'s left foot and blew it\'s head off. It\'s not a lot of variety actually but for a unit that\'s mostly looked at it adds a bit.
