1.- Read Duke of Malbrough link ( the third one), an already enlisted soldier was able to get the C. O. status, briefly he said that he turn out atheism recently, so he didnt use the religious issue but the moral one. Saying that his value now are against killing poeple, whoever they are, he succeed but it wasnt so easy.
2.- If the C.O. procedure is not knowed ( even eirey didnt know about it, and i think he serve in the army) then it could explain why soldier choose the fugituve insteed of the legal way. I mean, if you follow the procedure given into D o M link, it look feasable, not easy, but feasible. But how many soldier know this C. O. procedure, very little, because only 10 % succeeded in the first golf war, the others 90 % fail, because they didnt follow eactly all the procedure. And i bet you cant trust your officer to give the right information.
