What Does This Mean? USMC on Police Frequency?

hazmat? that doesn't sound good

getting ready to kick in the front door
of a P lab ?
well that would account for hazmat

Well the HAZMAT is the one of the three which I'm not really sure how unusual it is. I figure the PD does have a HAZMAT team for chemical spills and what-not. Reserve 101 could refer to some police reserves or something.

But "Marine uniform" is definitely interesting, and obviously appears to imply the USMC. The fact that Hazmat and Reserves were checked immediately after "Marine uniform" is what made me decide to list them too.

Marine could mean it has something to do with the water. Maybe busting a lab in a house boat or something.

Sure. Except I used to be exposed to these frequencies daily at work. I've never heard "Marine uniform" before, nor have I heard of "Reserve 101." Plus that's the only unit which has that peculiar designation, "Marine uniform." No numbers. It clearly sticks out.

And yes I've heard this particular shifts radio checks before on multiple occasions.

...any terror drills reported, sometimes this is that...

The Marines could have just been on the wrong freq. and doing some exercise. I doubt it is anything. Or it could mean DOOM!!!!

No that was a radio check. The SLPD were contacting all units attached to that dispatcher to ensure their radios were in working order, and "Marine Uniform" was one such attached unit. Not a mistake.
