Note 422 — Chapter VIII · Marking Time (April-June 1953)

Relief from the Eighth Army defense line provided the first opportunity for expansion of the 1st Marine Division amphibious training to regimental level. Amphibious training in battalion-sized MARLEXES had been under way since June 1952, upon transfer of the Marines to the western coastal sector. This had, in fact, “produced an extra dividend as [their] amphibious retraining program, conducted throughout the summer in the Tokchok Islands, was apprehensively observed by the enemy.” Field, NavOps, Korea, p. 430.
