Standard as in 'Oh noes vampires are real and I have to kill them now!' or standard as in 'I hunt Black Court for a living and I love my job!'?
For the first, wood, garlic, more likely than not guns, knives and anything else a terrified person can scrounge up in a hurry.
For the second:
Catch satisfiers(Stakes, garlic, fire, a religious icon that can be used with a temporary or permanent Faith power, map showing the way to the nearest source of running water in case things go bad)
An armored vehicle of some kind to use as a mobile shelter
Dispersal agents (a shotgun with flamethrower shells, canisters of pressurized garlic water, holy water filled pressure washer,etc.)
Reliable mundane weaponry for unexpected enemies
First aid, maybe some impromptu surgical equipment for serious injuries
Shovel (for hiding bodies)
Custom armor (Throat protection is a must)
Fake licenses and IDs
Contact information to other hunters, survivors, researchers, anybody that knows and might know something useful, really
Extraordinarily bright lights with remote trigger, in case they have the chance to set up before a fight. Maybe mounted to the vehicle?
Friends, i.e. other hunters. That they have trained with before, preferably. Teamwork is the best equipment, particularly in DFRPG
Possibly, but less likely, the tools needed to create custom explosives. Why fight the BC when you can just explode them?
