1. FA 1921 Thompson with the 100rd drum and a bandoleer of sticks.
2. HK 21 with a scope:
Always did like the idea of a belt-fed sniper MG.
3. A Walther PP in .32 found in shoulder holster, when the news media wished to photograph my band of merry zombie-slayers.
4. A 1911 in .45 in GI belt holster, with CT lasergrips - just to see if lasers bother zombies or not.
5. Walther 2000 - really neat looking gun, very compact, semi-auto.
6. Barret M82 in .50.
7. Webley Mark VI cut to .45 ACP, again for photo-ops.
8. Russian OTS-38 revolver, because they stole my idea for the silenced revolver.
9. Mauser HSc.
10. American-180.
11. Stechkin machine pistol.
12. Accurized .30-06 Garand with a scope.
13. Lever-action in .357 magnum.
The most important thing in such an environment is for the colors to look good together. It's not so much HOW you do it as it is how you LOOK when you do it. Photo-ops alone will win modern wars.
P.S.: This would all be carried in the classiest-looking assault wheelbarrow I could find.
