An arsenal?

Cops bust a drug dealer with what they call an "arsenal" and "more ammunition than I've probably seen in my life," says the cop.

What did they get?
4 ammo cans of ammo
5 handguns
3 shotguns
1 AR pattern rifle
1 SKS
and a bolt action rifle.

This is an "arsenal" and more ammo than the cop has seen in his life? I've taken more than that to the range on a Saturday. If I have less than 10 military cans of ammo on hand, I am low on ammo.
