For close-in troop support, helicopter and fixed-wing gunships were preferred. Requests for fighter-bombers were very rare. One air liaison officer stated that Thai ground commanders did not consider close air support a necessity during an engagement. They tended to request it only after contact had been broken off and friendly troops were a safe distance away from the strike. Thus, it became the job of the liaison officer to educate the ground commanders. With one of the two Thai brigades rotating every six months, the education process was a continuing one. As part of the education program, the U.S. Army and Air Force conducted a bombing and napalm demonstration with the Thai observers placed three kilometers away. Even at this distance the results were very palpable and unnerving. Thereafter, as a result of this experience, Thai commanders invariably pulled their troops back approximately three kilometers away from the target before calling in air strikes.
Last Years of Assistance
In December 1969 the effects of the withdrawal of the Philippine Civic Action Group, Vietnam, and publicity given the activities of the Symington Subcommittee were felt in Thailand as elsewhere. The United States had welcomed the decision of the Thai government to contribute troops to South Vietnam and was willing to compensate it by logistical support and payment of certain allowances to Thai forces for duty out of the country. These facts led to charges and countercharges regarding the expenditures of funds supporting the Thai division. On 19 December the Bangkok press reported that some twenty government party members of the Thai parliament had signed a letter to the prime minister urging the withdrawal of Thai troops from South Vietnam. The reasons given were that the situation in South Vietnam had improved as a result of the U.S. Vietnamization program and other aid, as evidenced by U.S. cutbacks, and that difficult domestic, economic and security problems existed in Thailand. No reference was made to the "mercenary" and "subsidy" charges of the previous few days. On 21 December Thai Foreign Minister Thanat Khoman told newsmen that he had considered the withdrawal of Thai troops "because the United States recently issued another announcement regarding further withdrawals." He also stated that the subject had been discussed with South Vietnamese Foreign Minister Tran Chan Thanh, and had been under consideration for some time. The minster was cautious on the subject: "Before any action can be taken we will have to consider it thoroughly and carefully from all angles.
