Mods please excuse me – I’m going to attempt to describe this as politely and non-graphically as possible while sticking to the truth.
I didn’t serve but I was required to pay a few visits to Lishkat haGeyus before they decided apparently they weren’t interested in me (oleh married with a kid already). However I can speak from my “time” served in the various offices and waiting rooms there. I saw a lot of hormonal teen soldier boys and girls flirting and hanging off each other. The girls’ desks were plastered with pictures of themselves and their girlfriends at the beach (with beach appropriate swimwear) and the guys desks were covered in hand drawn sketches of ladies wearing somewhat less than beach appropriate wear (or lack thereof). How am I to believe the bases are a kosher and tznius environment when that is what greets you before you’ve even signed up? FYI this was in Yerushalayim Ir hakodesh where 90% of the other guys showing up for tzav rishon were charedi/chashidish bochrim, not Afula or something.
