According to this article the guards are 2.23m / 7'4" and 2.36m / 7'9" tall. The taller one on the right is standing a bit closer to the camera, so I'll use the other one to measure the prof. Allowing for a bit of imprecision since it's hard to tell exactly where the guard's heel and head are under his clothing, I get the prof being 80% of the guard's height. This puts him at a pretty ordinary 1.79m / 5'10"
