Officially yes, I agree, at least visible marks were not tolerated much however there was a strong culture of silence. The military was not much more advanced than the larger culture. CaptainObvious seems to want a bizarre mix of conditions is all. The attributes he ascribes to the 'left' seem disconnected with any reality. Off base families will be as bad as anywhere, worse with PTSD etc. https://www.domesticshelters.org/do...on/the-facts-about-abuse-in-military-families
Additionally, if it was found out that your wife was being abused (by the other wives) they went to your CO and that pretty much stopped one way or the other.
I'm not trying to make a tit-for-tat point here but I know from a girlfriend's family very little was done. Of course it depends on the CO but don't expect much. My sister-in-law grew up in a home where she and her two brothers had to go to bed when their major father did, often 6.30pm (as older teens & when in college) and would catch a beating for a whisper. The man was a tyrant and they were fortunate he died in his 50s. Things are not what people like to think. As you can see mentioned here, even when it was noticed the response can be very light touch. https://www.theguardian.com/us-news/2017/nov/07/us-military-domestic-violence-gun-database Above directly relevant to Texas, reporting.
It certainly depends on the CO, you're right. Also depends upon the unit. Things have gotten a lot better.
All of the mass shooters I am aware of recently have been either muslims or leftwingers. Unless you count the FBI at Waco.
