I'm afraid unless you have a few Soviet RPG's, your under-armed.
I believe Craigslist in Libya has a few.
Hi Vader,
I tried a German Panzerfaust, but unfortunately it was too long for even the door pocket on a C126. A LAWS rocket would be about perfect, but as you can imagine they are somewhat difficult to procure here in the US (even in Texas). An MP40 is a decent compromise -- the ammunition is easy to acquire (and not too bulky), and having a few 30-round clips on hand provides good ability to sustain firepower when needed.
I think even a more preferable weapon for my C126 would be a Sten Mk 2, or a British Sterling given the "side" position of their magazines. Alas, something to consider acquiring for the future.
My Vietnam-era XM177E2 carbine (US Air Force variant of the M-16) would also work excellently, if I was able to source proper rounds for the M203 grenade launcher. These are what the Navy SEALs used in that conflict.
Another good option would be the M79 grenade launcher, otherwise known as the "bloop tube." The bloop gun is pretty good because its range is around 350 meters as opposed to the M203 on the XM177, which only goes out to ~150m. The sound of those firing is just bitchin' !
Cheers,
Gerry
P.S. I guess that for you, the lightsaber provides the best compromise between portability and packing a mean punch...
