1st Armor- Edged weapon armor like correction officers use in prison. At least the arm gauntlets and around the neck area.
2nd Protection- Rain gear or biohazard suit to protect from splatter- things are going to get wet with more than just water. Leaning more towards the rain suit.
3rd Food- MRE's Gotta eat when not on the move.
4th Water- Camelbak and some purification tablets. - gotta plan on things going fubar at the pick up point
5th Weapons- M1carbine- you can carry alot of its ammo, it folds up, it's accurate, and you can fire it with one hand if you need. 9mm Pistol clip fed like a beretta or even a smith would do. Something light. Preferrably silenced.
6th Tools- Firemans access and overhaul tool. Gets you into buildings and really has some sharp points to open skulls with. Can be used as a walking stick. Machete, chemlights, duct tape, a map, compass, poncho liner ( it's only the best made blanket in the world) ,a good pocket knife, a lighter, a deck of cards, some nestle's quick and a ham sandwich on the way out the door from the snack bar.
I picture beginning this from the gander mountain store in town.
