HE OBJECTIVES OF THE TRANSPORTATION STUDY, WERE THE DETERMINATION OF THE OFF-ROAD CAPABILITIES OF CERTAIN ITEMS OF EQUIPMENT AND THE EVALUATION OF Army aviation resupply, evacuation, and aerial navigation techniques used in support of a ground force operating in the tropics. Four areas which were selected as test sites exemplified various tropical environments, secondary jungle, virgin jungle, uplands or mountains, and grasslands. The operation at each area was one phase of operation TROPICAL WET. The major items of equipment tested were two cargo carriers, amphibious, five trucks One set of Jungletrac, two transporters and two helicopters Tracked amphibious vehicles used in support of jungle operations were available with an undeveloped potential. Light cargo helicopters were operated in tropical environments with little loss of efficiency. Communications equipment ANPRC-10, ANGRC-9 was unreliable and incapable of attaining rated ranges. Use of more powerful ground radios in conjunction with present helicopter equipment would enable a supporting aviation element to locate a ground element. Transportation support of military operations in tropical environments were possible in all seasons. Land navigation was difficult. Logistical support of ground element by an aviation element is contingent upon adequate communication between them.
