But it doesn't. Everyone's elbow is hinged the same way. It only has one plane of motion relative to the upper arm. The upper arm, with respect to the shoulder, has 3 degrees of freedom (up down, left right, twist). His armor doesn't change this.

His credentials are just bogus. He's basically looked at a lot of photos. That extra "flap" of material that "locks" in place for an extended arm is BS. It's there to cover the elbow when the arm is cocked.

The #1 advantage gained by his equipment is hugging the plate. Most (or all) his points are bogus and misinformed.
