My particular Vickers has been modified to shoot knives. The MG42 shoots small missiles that split open to fire the following individual melee weapons at over 2400 fps: a club, a cane, an axe, and a katana. All have a +2 damage amplifier.
I want to pick up Ruger's new RL98 Riot Lion in .367 that debuted at the 2009 SHOT show. It boasts a 48 (yes, 4-8) round magazine firing the revamped Cobra Strikeforce .367 round with ballistic bezels. Paired with an ACOG and Leupold's Mark 4 8.5-25x50mm LR/T M1 illuminated reticle metric riflescope, and Nighthawk's Gen. 4 Nightvision goggles (the goggles are a bit much at $7600, but it WILL BE MINE!) and any foe you come across is worm food. Couple this with Remington's seven shot 10 gauge Nitro Stallion with the standard Ghost Ring Holographic front sight, and you can take all comers, large and small, living or undead.
Ask LRM about the new 2009 series Tactical Rascals, those things kick ass. The 2009 HG has 26" Michelin Super Mud Whumpers and six wheel independent suspension. There is a mono arm that is modular for attaching all seven of the Tactical Rascals All Terrain modular EVAC tools. One arm, seven tools.
I'd look into Verizon Wireless' headsets that came out just before Christmas. 48 gigabyte upload speeds for the SATCOM (satellite communications) features. Whisper boom mike and BOSE Dominion earpieces make a 7000 kilometer communication sound like you're sitting next to each other at McDonald's! These things are just now being made available stateside, though they've been in Japan for, like, three years. Check it out.
