and that's why in my mind carlos halfcock who, you know, i think it's 93 confirmed kills, i think he is the greatest sniper ever in history. and not just america, all over the world. he's the guy that would go in by himself, you know, sneak in, take his shot with a lot less, you know, capable weapons than we have today and optics, but he would take that shot and then sneak back out undetected. and i think that's the true measure of a sniper is being able to get in, identify your target, take the shot and get out. >> host: jim erickson sends in an e-mail to you, mr. kyle, how many unconfirmed kills do you estimate you have, or were all of yours confirmed? did you ever train with the m25 white feather rifle? >> guest: no, i never used that rifle, and as far as the unconfirmed kills, you never count those. it's -- there's no point in trying to keep track of what could have been or might have been. you're just wasting your time. and your whole thing is you're out there to try to take, you know, these bad guys off the streets and make it safer for your guys and allow some more of your guy
