That’s unlikely. You need to get grants from the federal government, chiefly the DHS, to get money to buy major equipment. There ain’t anymore federal grants remember. Small volunteer, (70% of all fire depts in the US), services are especially reliant on those grants to replace major assets.

You act like you don’t understand police departments need grants to buy those things also.
