Briefing notebook spreads for 20, 22 and 24 February 1970. By this stage of Captain Bobby Ross's tour the daily communications plan had grown to include separate admin, ARVN, medevac and survival radio frequencies alongside the mission nets. The entries record teams marked STRATA, the Vietnamese-manned reconnaissance element run under SOG, extractions flown by Kingbee, the Vietnamese Air Force H-34s that supported SOG, and a 105-man element consistent with a Hatchet Force company. Abbreviations such as WASH, WYM and ILL identify the U.S. state-named recon teams of Command and Control Central. Project: 219835
