DADT Survey Findings
I would not equate "leaving sooner than planned" or "considering leaving sooner than planned" to equal a wholesale loss that would lead to national conscription.18.5% of all Service members reported they would consider leaving sooner than their current intentions if repeal occurs. This is the group of Service members who “switched”their military career intentions when considering DADT repeal. They were not considering leaving, but said repeal will cause them to “think about leaving sooner” or“leave sooner.”
Among all Service members, Marine Corps members were most likely to say they will leave sooner than planned or will consider leaving sooner than planned (38.1%)
I personally never saw an officer ignore a violation of the UCMJ. Any officer that does is putting his career on the line.
I caught a soldier ass ****ing a chick in the barracks one time and had him locked myself. He was charge and convicted of an Article 125 and an Article 92 violation and dishonorably discharged. Had I just closed the door and went about my business, i would have been looking at a courts martial for violating Articles 78 accessory after the fact, 192 failure to obey and order, or regulation, and 134 all disorders and neglects to the prejudice of good order and discipline in the armed forces, all conduct of a nature to bring discredit upon the armed forces, and crimes and offenses not capital, of which persons subject to this chapter may be guilty.
Sorry, but I wouldn't put my career on the line for some asshole that can't follow the rules. Nor, have I ever known any officer, or NCO that was worth his salt, that would.

Keep your religion out of other people's marriages.
We had a good sailor who developed an alcohol problem when his wife left him. He showed up drunk a couple times. Rather than boot him out, we handled things in command and talked him into volunteering for the rehab program(forget what it is called). He never went to a UCMJ, his showing up drunk never appeared on his record.
Sex in the barracks was commonplace, and our officers knew it. We had two semi openly gay people over my time in the command, one was a yeoman who was the skippers secretary. This was prior to DADT.
I think you would be surprised at how often commands look the other way on things.
BBC NEWS | UK | Army acts to promote gay rights
Besides that, this isn't the UK, nor does the British Army have the same military regulations that the United States military has.
Your source makes no mention of retention post-gay integration, so it does not address what I said in any way. Also, while the UK does not have significant problems with gays serving that is not the same as no problem. Trying to improve is a positive trait.
