The ruck is rigged in front of the thighs and is released on a 15 foot tether as the jumper approaches landing. The manner in which the ruck is rigged make it difficult to walk and so the jumpers waddle. In the film, the ruck is seen between the legs because of the straddle. They then jump with legs wide to achieve aerodynamic stability.
There is a difference between standard "mass tac"static line jumps and free fall (tis appears to be high altitude/high opening or HAHO). Traditional static line jumpers will keep feet and knees together but freefall need to have a different aerodynamic stability and so go out spread.
