They aren’t going to throw away a career for a medical. My sons unit has a candidate who was medically removed (typhus, don’t ask) the previous evolution but given another shot at it with my son’s evolution. I believe most units don’t want to dismiss anyone but want to tip you enough over the edge for you to know it’s not for you or give you that motivation to scramble back up over the cliff and take it to the next level. Sometimes that tip is a more of a shove, but that’s where they want the leaders to come from. While I have faith my son will place well, they started with 18 and down to 9 for a 4 week program. And only 5 spots. I’m taking the position that the branch will put him where he’s most needed, whether he wants to be the or not. And that’s what’s best for the unit. Best of luck to your son, and lots of bourbon will help you between now and Saturday.
