OP: Iron Hammer Two
By 1967, as a result of the success
of the SEALs in the Delta region, their numbers in Vietnam were
increased substantially. Their major base was at Nha-Be, and SEALs
maintained mobile bases on barges on the waterways of the Delta .
From these mobile bases they mounted hunter-killer and intelligence
missions throughout the region. Occasionally they were called upon
other missions as, underwater demolition, reconnaissance,
ambush-snatch, raids, special security duties and frequently acted
as scouts when large scale Riverine operations were mounted.
