officers are not rocket scientists on the intelligence scales.

Few people are. Officers can be quite intelligent and well-educated people. The military academies are some of the best educational institutions around, with selection standards more comparable to Harvard than community college. In one of my own communities, Haskell programmers, the top purely functional data structure guys, Okasaki, is a West Point instructor.

You should however note I was referring to the soldiers who actually commit the violent acts, thereby frequently getting themselves maimed or killed; these military personnel are stupid because it is stupid to put yourself needlessly into a dangerous, life threatening situation.

There's still a floor on their intelligence. Some of the research I alluded to showed that IQ advantages show up even in manual training and basic combat skills - the higher your IQ, the faster you learned and the higher your ultimate plateau was.

(This is consistent with the little I've read about top special forces members like Navy Seals and other operators: they tend to be extremely intelligent, thoughtful, with a multitude of skills and foreign languages. Secrecy means I do not know whether there is a selection bias operating here or how much is PR, but it is consistent with the previous observations and the extreme standards applied for membership.)

for me it is a derogatory term indicating a dim-witted pant-hooting grunting ape who doesn't have the intelligence to realise joining the army as a Grunt is not good for survival thus some would say stupid but I realise the Army doesn't accept clinically retarded Grunts...Do these dead men look intelligent?

Are you trying to troll me with awful arguments here? If so, I'm not biting.

I wonder if they were signed up for cryro-preservation?

To a first approximation, no one is signed up for cryonics - not even LWers. So mentioning it is completely futile.
