Same thing here about not wearing the uniform off base.
1971,Ft Lewis,the officers said it was dangerous to
go in Tacoma with VN service awards on you alls dress
uniforms. Hell,the bus transporting us had steel mesh
on the windows to stop stuff thrown.
Back in the late 70s or maybe the 80s a jet plane was highjacked and flown to Beirut (TWA?). Highjackers killed a US sailor and dumped his body on the tarmac. I don’t know for sure if he was in uniform, but it seemed after that, not many service members wear the uniform while traveling.
