A member of a MARSOC Marine Special Operations Team (MSOT) covers fellow MARSOC operators from a RHIB craft as they board a vessel during a level 4 VBSS Maritime Interdiction Operation training exercise.
Level 4 VBSS is categorized as an actively opposed boarding of a non-compliant vessel, such as a pirate-held ship.
Other Maritime Interdiction Operations that MARSOC MSOTs train for include retaking gas and oil platforms from hostile forces.
The Marine in the foreground is wearing a MICH 2000 helmet over a comms headset.

The helmet also features a chem light mounted on top.
