Peters has written some er... interesting material recently, including a deeply critical piece on UK ops in Basra. Apparently, we should have gone around killing anyone we even suspected to be an insurgent. As an advocate for re-enacting My Lai he wasn't that persuasive.
Also, although his rank and past service with the USA is often highlighted, his background is entirely in intelligence. An American officer late of my acquaintance branded him 'a REMF with no idea of how the front line works'. I've always wondered whether that was an accurate comment or a misunderstanding by said acquaintance (background in armour [it has a 'u', chaps...] and had shot at a few people)? Any knowledge from American Ppruners?
