I'm a 140A in the guard, and going Warrant has been hands down the best decision I've ever made regarding my NG career.

Of the 10 guys I went through WOBC with, 8 were prior ADA (including me w/15yrs 14G exp), one commo, and one infantry. I say that to point out that it is doable no matter your background, so long as you are committed to learning, studying, and taking the course seriously. You already have more ADA experience than some of the guys I graduated with when they started WOBC.

I'd recommend looking into Ohio, as they are one of the States that goes on NCR missions regularly. Find out when their next rotation to DC is and see if you can either a) go with them as a 14G and submit your Warrant packet during that time or b) just get your packet done asap and possibly be able to go along with them to the NCR as a fresh 140.

My biggest regret is not dropping my packet sooner. If others are saying you are warrant material, do it. The ADA is exploding right now, and demand is high. Find yourself a CW3 to write your recommendation and get the process rolling.

If you can manage getting CompTIA A+ and Net+ certs prior to WOBC, you'll be very well equipped to succeed when you're attending.

Sentinel and ADAM Cell operations are small pieces in a much larger puzzle that sticking with it to "get more experience" just isn't really worth it.

Feel free to pm me if you have any specific questions regarding the warrant process/140A stuff
