If you really were the CO of the mountain sites then you did a **** job if you didn't know any of this was going on!
Since you quoted his entire post is it unreasonable to suggest you actually read it????
He didn't say he "didn't know any of this was going on!"...he actually gives a pretty good account of it!.
What he said was no formal complaint was made...which is an entirely different thing.
Since you were a SNCO and somewhat "closer to the coal face" so to speak, maybe you should not be chucking stones in your glasshouse, no?
