I went through in '89, well prior to the 18X program. Most of us in SFOT (predecessor of SFAS) were in our mid to late 20's-early 30's. Because 99% of us came from the regular Army and were already E5s and E6s...and a few E7s. Age is relative...being in optimal shape, being able to push yourself beyond your limits, and never quitting is what's going to carry you through the 21 days of selection. But rest assured, as others have already indicated, you are always being evaluated. When you can't carry your weight on an A team, you'll be shown the door.
