I believe that is the annual eval done by his TX commander while he was in AL. The evaluator writes that 1LT Bush was not present so can be evaluated by the author. Pretty much SOP stuff, but the peacenik liberal tree hugging draft dodgers don't understand that - they see it as being AWOL.
"May 2, 1973: Bush?s superior officers William D. Harris Jr. and Jerry B. Killian, wrote on his yearly evaluation form, ?Lt. Bush has not been observed at this unit during the period of report,? and that a ?civilian occupation made it necessary for him to move to Montgomery, Alabama. He cleared this base on 15 May 1972 and has been performing equivalent training in a non flying status with the 187 Tac Recon Gp, Dannelly ANG Base, Alabama.?
