The IDF is pretty laid back, brother. But that is a tad harsh.
Laid back in the "not-as-formal-spit-and-polish", I get. Kinda like we were on the boats underway.
But make no mistake, there're a few senior NCO's who should be chewing some serious ass. I know if I wore a t-shirt like that on the beach or underway, it wouldn't be worn for long.
