Best gunship ever (probably impossible, but fun to dream):
1. AC-130J
2. Eng, Nav stay on
3. MX-20s + . . . other sensors
4. Better radar
5. Helmet-mounted targeting, i.e. HUD built into the visor, F-15/JSF-style
6. Avenger cannon + 40mm + 105mm + MORE AMMO
7. Hellfires.
8. Defensive shit we can't talk about here.
What the heck COULDN'T we kill then?? Maybe a concrete bunker 6900 feet underground, but everything else is TOAST.
