The WI Department of Justice requires bi annual recertification in the 5 tactical areas of LE training this involves Defense and Arrest Tactics (DAAT), Pursuit Driving, Emergency Vehicle Operation and COntrol, Firearms and Professional Communication.
The two areas you seem to be referring to is DAAT which is defense from a combatant. This is not training in hand to hand combat but focused strikes to stop an unarmed threat and make an arrest. Handcuffing techniques are also covered in this area as well as baton, oleoresin capsicum (OC) Spray and TASER. The second area you are referring too (deescalation) is under professional communications. This area focuses on talking with citizens, suspects, and aggressors so as to have a calm resolution to a situation and not have to use the techniques learned in DAAT and Firearms.
There are additional classes not taught by the DOJ, but by outside private agencies that Departments will pay to send officers too. Some of these could be construed at hand to hand combat, and ground fighting techniques to be used in a defensive situation. There are also verbal judo classes which enhance an officer's skills in talking down a situation. These additional classes are all optional and not necessary to maintain certification.
It is also Department specific if they want to do additional training in DAAT and Professional Communications at things like quarterly trainings, in house recertifications or just regularly scheduled trainings. I cannot speak to specific Departments because they vary, many based on budgets.
I don't work for MPD so I really can't speak for them, but I can tell you myself and every officer I know would much rather talk a person out of anything than go hands on with a subject or use any of the tools on our belt beyond our handcuffs and radio. If I use a tool or go hands on, I get a mound of paperwork that I can usually avoid by being nice to people, even if they are less than polite to me. In the same instance if someone rushes me I have to act based on a lot of instant observations and information. Is there a weapon? Has this person verbalized a want to hurt me or others? What information was I given by dispatch? Is this person known to me as specially trained in MMA, or martial arts where they could easily kill me unarmed? Is this person 6'6" and 320lbs of muscle vs my 6'2" 190lb? or is this person 5'2" and 100lbs (lowering the threat)? A lot of things happen fast and we are always trained to verbalize before anything, announce who you are and what you want i.e. "POLICE, STOP!"
I've worked with MPD several times and each time I have been pleased with their professionalism and respect when dealing with the public. I hope this gives you some insight into training and procedure. The emphasis is always on deescalation but I would say the DOJ does not require a lot of training after the academy.
