How does an E6 have 6 service stripes?

Reserve/national guard. I met a 25 year specialist.

I don't understand the confusion. RCP ( Retention Control Point) is 20 years for SSG. So he's fine. Promotions are hard to come by in certain MOS's and getting slots for SLC are even harder. Not enough info to give you an answer why.

I know people that have been in 23 years as a SSG, even 19 years as an e5 buck SGT. Theres 12 year E4s out there. RCPs change by rank.

And how many years have you been in for?

Why younger than 36???

Or slow promotions

That means some where down the road the SSG GOT BUSTED DOWN THE ROAD FOR SOMETHING

Simple, you haven't been long enough to know that people screw up and get busted even late in their career... Don't try it...

I kinda of want to see you do copious amounts of un-authorized exercises for asking this question.

Something I haven't seen in the comments is that he's in the National Guard. I haven't read all the comments, I only saw the post a few minutes ago. But I'm in the National Guard, and it took 12 years to make E5. I'm an E6 over 20 now. I started off in the Guard for 18 months as a PFC, was released to active duty and and was a E4 in just a few months. I did 9 years 10 months and 18 days. That's what's printed on my first DD-214. The Army changed retention control dates of E4-Ps from 13 to 8 years and i was kicked out. My MOS was maxed out with 998 until the reduction of points to 798. With a 12 year break in service I joined the guard again and in about 3 months I made E5. I was the only one in my state in my MOS and made E6 in 2 years. Now I'm a 51 year old E6 over 20, sitting in Kuwait and still kicking butt passing the army PT test.
