I was in the pipe to go to SWAT school and had attended several TEMS courses when the CLEO axed the team. Several of us still cross train but the trend is going more towards the Rescue Task Force model endorsed by the IACP and IAFC, as it requires less training and exposure to potential liability than TEMS and "firemans with gunz".
Our FD is discussing the possibility of putting response kits in our ALS vehicles - basically bags with a bunch of TQ's, NPA's, and chest needles, as well as chem-lights and marking pens to indicate area status to other responders.
As for your question, although it onlyh comes out for training I have a Condor "Rip Away) Medical Pouch on my vest.
I've got gloves, 2 NPA's, an Izzy Dressing, a (now expired) hemostatic dressing, 2 Ashermans, a TQ and 2 14gx3" NDC needles in it. On the outside I have a Benchmade 7 hook.
All the PD guys were issued personal kits like the NARP IPOK and have CAT's or SOF-T's. They follow the military's practice of using the victim's supplies for the victim for CUF. I've steered them away from the SWAT-T, as it's never been subject to the same degree of documented study as the others, although one of the selling points is it's low storage profile. I also suggested they throw out the RATS that came with their range bag, but for additional reasons (see spoiler).
One of them is the issue of the company that sells the RATS copyrighting "TCCC" and applying "TCCC APPROVED" to their products, despite the fact that the Committee on Tactical Combat Casualty Care (CoTCCC) doesn't "approve" anything, they simply make recommendations, and that TCCC was in common use 10 years before they claim they first used it for marketing purposes.

My bag is set up more for TFC, and includes more gloves, 2 SAM splints, 2 1L 0.9%NaCl, 2 10gtt/ML drips, 2 each 14-20g angios, more NPA's, Ashermans, Izzies and hemostatic gauzes. Given that it's use is in the transition to "regular" EMS, I also have a stethoscope and BP cuff so the numbers nazis in the ER are happy.
It also includes team wellness and readiness supplies like ace bandages, cold and hot packs, band-aids, OTC meds and granola bars.
