Good point. Then perhaps this (Sorry, but I don't think SLUDG is QUITE necessary yet....even if the HOSE would make an EXCELLENT flamethrower):
Fast Forty of Flying Fragging Flaming Death
FFFFFD
This thing is not nice. No, really, it's not nice. Built along the lines of modern military equipment, this revolver-style 40mm grenade launcher utilizes a variety of ammunition, including HE, HEAT (Hey, you never know!), incendiary (NAPALM!), fragmentation (Nobody ever died from blowing too many things....wait a minute), and has provisional designs included for the creation of rocket-propelled variants and ABC Scrambler ammunition...should that ever become necessary. All the grenades can be thrown by hand if necessary, and will properly detonate on timer.
----In short, this is something we're gonna need---a nice, nasty, super-deadly grenade launcher. The incendiary is mostly a joke, but I bet that those zombies are fairly flammable, considering that their bodies are probably dried-out husks. All the other ammo is standard-issue in other armies, should be BEYOND easy. Rocket propulsion on the grenades would cut down payload, but as it's a 40mm grenade payload's not really an issue, whereas keeping the freaks at long range is a REALLY nice advantage. And of course provision for disabling those ridiculous mages should we ever deploy the scramblers. Guess we're going to have to find out whether or not those mages will have other effects, I suppose. If the mages become an issue, scramblers, scramblers everywhere.
