Currently a 31B looking to reclass into 15W, UAV operator. Can anyone tell me more about this MOS?

Fairly sure it is only open to non-promotable SPCs. Don't just look at the in and out calls- you need to look at the reclass requirements listed within the MOS Smartbook. If there is a discrepancy, the Smartbook wins.

There is absolutely no difference between an enlisted pilot versus a commissioned pilot in my view. Its a status thing. The army used to promote enlisted to WOs to fly the helos, not sure if thats still something they do though. i say let enlisted fly. Also why is it acceptable to wear glasses or corrective lenses after flight school but not during? ive seen more than a few captains and above wearing glasses during flights. I think that its just another measure to make the competitive field weaker.
