My brother has had to have neck surgery to replace a disk that was likely destroyed by many many miles off-road with a helmet weighing far too much.
This is one of the hidden costs to Reservists and National Guardsmen...the injuries that don’t show up til later and can’t be proven, but are pretty clearly from these situations.

It’s tough on the body, that’s kinda what you sign up for when you enlist. I’ve got aches and pains associated with my time in the USMCR, but I hurt with fond memories of serving my country with my brothers in arms.
