Who cares about the OTA storyline. As i clearly stated in the original post this isnt OTA. CA = New units, new factions, new names, new storyline.
Arm = (tenatively) Nova. Nova are not clones. You dont need to tell us the OTA backstory, it doesnt even apply. That is not a cockpit.
We are not using the PSG stuff, firstly its copyright of Arne, secondly its based on copyright of Atari and thirdly it doesnt fit the game we're making.
Its not an Orca. It is quite clearly a Banshee:

Ahh, actually, its more of a Hunter-Killer:

No, wait, its an Apache:
Or maybe a
talon?
The Orca and all following designs are mostly derivative of the Apache gunship, only with rotating vtol jets. C&C was made 4 years after Terminator 2, which is the first time ive ever seen those rotating vtol jets (though perhaps they predate T2). While they are kinda unique in appearance on the Hunter-Killer, the idea is obviously borrowed from the Harrier.
