Weirdly, I thought he seemed to have copied the sort of image / expression on the front of his book as some published ex SAS soldiers have. I don't know why he would do that (other than the success of Jason Fox et al and hoping to be taken 'seriously' like them) My feeling is that perhaps he felt that because their books were best sellers, then maybe his 'war memiors' would also be met with accolade. Except they worded their experiences very differently.
It's almost like cosplay. Yes, we know he toured Afghanistan. We also heard at the time that he was pulled out of the war due to him feeling his position in the RF may have compromised his fellow military colleagues.
I know people who served in Iraq, Afghanistan, and indeed my own grandfather who served in WW2. The narrative from Harry is disturbing. I've never heard the same sort of narrative from other military personnel.
He obviously has a lot of issues. He is the first to admit that. However, the way he is going about processing his problems is very odd. And his need to overshadow everything and everyone else is deeply concerning.
As others have said, those who are advising him do not, perhaps have his best interests at heart. Something he has previously accused The Palace and his family of.
