You think Intel is limited to British Officers alone, think again.
Meaningless to You perhaps, not to others effected from being in service.
Irrelevant to what nation or crown.
I think the main problem is your translation. What you're writing is not what you are meaning, and it's literally being lost in translation. I am not trying to mock your language skills. I would do poorly trying to write a cogent sentence in any language, and to anyone who reads my posts, often struggle with English, my native tongue. With that in mind, your comment did not make any sense in English.
An NDA, for example, is a legal contract used in business to prevent disclosure of proprietary data. It has nothing whatsoever to do with classified government or military information, which has legal restrictions regardless of consent or agreement. Other spelling issues are really meaningless and can be figured out, but concept mistakes made it impossible to understand your point. You're also not understanding what you're reading in my post. For example, I am an American, not a Brit. I am a military veteran, who had a Top Secret - Eyes Only clearance (one of the highest security clearances), even though I was not in Intelligence and did not serve in combat. I would dare say I know quite a bit about this subject.
I have had many veteran friends with PTSD from their combat experiences, and I myself also deal with fairly moderate PTSD, but not from combat. I understand that trauma well, and I think that is far more relevant to this game's story than any Classified information. It's not just the veterans dealing with PTSD, though all three main Veteran characters have it (Val, Els, McNab), but Vi has a rather serious case as well from the attack in her childhood. Els' father probably does as well, and openly discusses how his military service ruined him. I think it's sad that Val hasn't disclosed this conversation with Els, at least to this point, because I think it would be hugely cathartic and healing for her to finally understand the comment that she overheard which led her to run off into the military.
