I've seen F16, F15E, U28, C145, every 130 variant, etc etc guys come through gunships and all have been accepted and done well. The ones who don't do well and get the cold shoulder are the ones who show up and think that because they've been somewhere else, they know everything about everything. There are massive amounts of very varied experience in the gunship community and as long as that experience is used to make the platform more lethal, instead of dick measuring, it's received as a positive.
If you want first hand experience with high time 146 guys to answer whatever questions you've got, hit me up and I'll put you in touch
