Underwater Construction Teams

[1] Reflecting Seabee tradition, teams are expected to execute underwater construction anywhere, anytime, under any conditions.

Divers were taught in diving school how to fabricate a breathing apparatus from Navy MK-III gas masks for surface support.

[4] However, the divers of CB 96 used 1,727,250 lbs of dynamite to blast 423,300 cubic yards of coral for the ship repair facility on Manicani Island, as an element of the Naval Operating Base Leyte-Samar.

[5] During the Vietnam War at Chu Lai in 1967 MCB 71 had an Under Water Construction Team search the Tra Bong River for a missing Squad of Marines.

Sea Duty personnel are divided into three Air Detachments that deploy worldwide in support of both peacetime or combat missions as needed.

The Shore Duty component contains all of the staff and support functions such as Administration, Supply, Logistics, Table of Allowance Maintenance, and Training.
