Drop your rifle in the water and recover it 2 days later. Things like that kinda weed out the weak units.
Seriously, how the heck do you drop your rifle in the water and find it 2 days later?????
WTF?????
I don't think even an extra set of twin 80's would let you stay down that long!
Seriously though, I talked to a SEAL platoon chief in 1985 that had just left a job at Crane and was involved with the search for a new sniper scope for the M24. He said their subsurface requirements destroyed every scope submitted including the Euroscopes that were considered THE top-shelf glass at the time. Leupold was the only maker that went to work and engineered a scope (the M3 Ultra) that could hold up.
I've heard Marines refer to the Schmidt & Bender as the "schit and bendover".
