I think this is due to general decay in the army and not to injuries. There are more and more queers, office rats, Iq officers have dropped significantly, by at least 5%
Crossfit does not lead to increased injury, it is a myth. CrossFit develops the ability not to get injured in non-standard conditions, thanks to the fact that it trains the culture of movement and complex coordination. An untrained person slips and breaks his head, the athlete falls softly. It is better to dislocate a leg on the sportground than to leave life in battle.
