longarm - I don't know, but something with a good-sized clip and heavy stopping power at moderate range.
sidearm - Colt M1911: Good stopping power without a lot of bulk to carry around.
explosive munitions - Claymore mines. Plant them at head level and watch the shrapnel mow 'em down.
support weapons - Define "support weapon."
blunt or edged weapon - Longsword: Good reach, fast and versatile, and a lot of German swordsmanship involves cuts to the head so the technique alone works in my favor
armour/body protection - If we're talking slow, dumb zombies I'd rather go unarmored. Faster, better mobility, and what purpose would it really serve, anyway?
any other unorthodox weapon you feel may serve eg frying pan - Det cord or other similar explosive: something I can use to create roadblocks by knocking down telephon poles or by blowing out chunks of walls. They're ZOMBIES, it's not like the concept of going around is going to come to them.
