I have some background knowledge here that might clean up a couple of detail fragments.
It wasn't Military HQ (to be honest never heard of such a place by that name).
MGO or Military Gamer Online merged with Wargamer back 2-3 years now. MGO and Wargamer were both acquired by Matrix Games (which is basically David Heath).
MGO is now just a name from the past much like Avalon Hill is now just a name and not a place.
Wargamer is still a forum and web site, and is useful in many ways, but being "owned" by Matrix Games, naturally some just assume it's a sub section of Matrix Games. Their recently stated interest in a print magazine will no doubt be an interesting development.
Where Warfare HQ (now Armchair General and Strategyzoneonline)

differs from Wargamer, is it is not owned by a company that produces gaming software (to my knowledge). They truely are just a group of dedicated military enthusiasts (I am one of them).
I personally think they are more likely to be free of company based bias due to not owning any allegiance to one.
I happen to know your company is well thought of there as well (Annette's remarks are always enjoyed for starters
)
