12 of them? Naw, maybe one....and now this. Coincidence? Naw.
I was assigned to a Mobile Combat Comm unit, just before I arrived the unit did a deployment to Thailand. Before hitting the field they stayed over at hotel and a bunch of guys were picking up the local girls. some were bringing 2 and 3 back at a time. First Shirt and Commander would sit in the Lobby and watch them bring them in but said nothing. Then somehow a wife back in Okinawa caught wind and things heated up, then a couple wives got STDs when the guys got back home.
Ended up with a few Non Judicial Punishments.
Easily can happen to a poorly run outfit with a weak or complicit officers.
In this case sounds like the groups officers were central in the nocturnal activities. So why wouldn't the lower rank guys take advantage of a situation...
