Don't get me wrong. My vote by no means indicates that I think your article is bad. To the contrary, in fact. I just find that it is probably not the best note on which to start as far as the first Bombers' article posted on the main page, since I don't think a basic summary of the history of Gohma captures the essence of what the group exists to do. This is very well-written, though, especially considering English is not your first language!
Also, just as an aside about Armogohma, I'm fairly sure that the Japanese name is literally "Armor Gohma" (and, indeed, a look at the Japanese microsite confirms that it is "shelled Gohma"), which is probably what explains the appearance and the English name.
