WK,
If your hell-bent on being a CSO then Active Duty is really your only option. The B-1 and the F-15E have CSOs. The guard probably has ABMs, but I'm not completely sure. Commissioning is plausible, but if you take the Active Duty route, then you'll deal with a recruiter and he'll get paperwork ready for the OTS (Officer Training School) board. If you get accepted, then it could be a long wait (1 yr) before you even start. If you want more info on that whole process, I suggest visiting Airforceots.com . When I went through OTS back in 06', and that site provided me some good information on the entire process from beginning to end. If you have any questions on being a B-1 CSO, message me. Cheers
