Hi, the neck should be almost as wide as the head, and the head is a little too big. I have no problem with him not beeing some muscle dude, a lot of army guys are not.
As for animation suggestions. Here are a few:
Standing still
Walk
Run
Jump
Climbing (ladder, wall)
Crouch
Walking while crouching
Lying flat on stomach
Crawling on stomach
Shooting with pistol
Shooting with rifle
Shooting with machine gun
Shooting with submachine gun (could be the same as MG)
Shooting with bazooka
Throwing grenade
Slashing with knife
(all of the above in standing, crouching and lying positions)
Roll side ways
Die (more than one way would be cool)
Falling from great height
