Copy, I've been a flyer for a few years and in flying squadrons, I understand what you're saying because I see it daily. However, SMSgt LRS guy who's at the Senior NCO Academy doesn't know this gem of information, and that's not how non-rated Officers act. So by saying off the bat Lt's don't salute each other to a bunch of non-wing wearing SNCO's you're going to get weird looks and "mentored" about how it's not right to do so.
Technique Only
So, "only a few years" applies to Lt's?" Sure.
