Oggin,
I think you'll find that the Herc fleet can deploy a brigade-strength force, including vehicles, equipment, weapons and ammo, onto virtually any piece of land, anywhere in the world, by day or night, in virtually any weather (theoretically), in the space of 5 minutes. Now THAT is offensive capability.
I was once asked by a Fighter Controller, during a bar banter session in MPA, exactly how I could evade detection and destroy his radar site. I offered the prospect of 80 hairy arsed paras, dropped the other side of the hill, out of his sight, to come and say hello and ruin his day. I think you'll find that's pretty 'offensive' (much like my banter, it seems, to the sensitive boys of the FAA) - after all, humans are the most accurate and reliable guided weapons available.
