Navy SEAL Combat Swimmers - Swim Pair
A pair of US Navy SEAL combat swimmers wear rebreathers and use compasses fitted to swim boards to navigate through murky waters. SEALs typically operate in teams no smaller than two (a 'swim pair').
The SEALs are wearing LAR V Draeger rebreathers, closed-circuit breathing systems suitable for clandestine operations in shallow waters .
