Eh, training is training I guess. Back in the 1990s I was part of an Army OPFOR group that was specifically training one of the armored brigades on how to kill police during mass arrests and gun confiscation.

The main difference of course was that wiping out a police force was just fine as long as it was Serbs in Kosovo, but I remember how the NATO standard rule of engagement and law of war briefings went.

A "neutral" military or paramilitary force did not have permission to engage to prevent gun confiscation, but gun confiscation was one of the recognized indicators that human rights violations were coming up. Once there was gun confiscation, then mass arrests of obvious non-combatants would follow (like rounding up kids in a school).

The green light indicator in the scenarios which changed the status of the police from lawful force to "uniform of the enemy doctrine" and actually not even under much legal protection was summary executions in the street. I remember because I was playing the role of Serbian cop on lookout duty when the "commander' executed someone on the street below. As soon as that took place (I was unaware) then all hell broke loose from the armored vehicles and wiped us out within 30 seconds. I had thought the scenario was going to play out for a few days with a "siege", but I was told that as soon as the "human rights violation" was verified by observers, the military force had the right to wipe us out, go to chow, and head back to the barracks before dark. None of that stand around and observe and discuss shit.

It looks to me like maybe the NG unit in Ohio was experimenting with a further playout of the other side of that same type of scenario.
