My 1st commando was a male of body type 2. When I got Sprint, I noticed that my character, while holding the cannon in his hand and sprinting, had a weird running animation like he was running through those car tires back at boot camp.
Horrified, I instantly made a female character of body 2. Astonishing, when I reached level 14 and got Sprint, the same animation was much better and the character wasn't running through the tires. Go figure...
