BTW, since it is feck'n MARS, I'd say there's a pretty high Army presence, similar to that of Reach/ODST, as such, [url=http://halo.wikia.com/wiki/AMX-4]expect a fairly high number of cheaper and quite capable UH-144[/url]s and a smattering of the lighter Hornets to be attached to assist the ODSTs.

In Halo nomenclature, VMX = Marine, so AMX = Army... seems logical.

Also, unlike the other Spartans, S-III was an Army program.
