As intimidating as a strong man is, they really wouldn’t have the endurance needed to be soldiers. Arnold was big, but at 240 lbs, he’s at the upper limit of strength versus oxygen consumption efficiency. Those strong men are 350 to 450 lbs with a lot of muscle. Not ideal for running around, gathering data, and firing weapons. Though, I suppose they could carry a lot of ammo and a big gun, for what that’s worth.
On topic. Yeah, they should have probably included red hair, along with the others.
