This is a condition common to those that have served/are serving for the Territorial Army in which they delude themselves with grandeur and demand respect in day to day "civi" life based on the fact they are in to TA.
People with this syndrome do not suffer since a secondary symptom is being utterly oblivious to how they are despised by the real army and civilians alike.
Not all members of the Territorial Army have this syndrome, but those that do can be detected by the fact they will bring up the fact that they are in the TA within seconds of starting conversation.

Dean: Ahh, umm, I'll have a double whiskey and lemonade. We don't get chance for all this lazing around you lot do in the TA, this is the first drink I've had in five months.
Bartender to regular: What a cunt.
Regular: Yeah, TA Syndrome.
