For officers to prevail, training must include stressful situations that test each component of the OODA loop.

Rock, paper, scissors
This drill requires two shooters with duty gear, a referee and simple paper targets made from clip art.
Shooters are given a target sheet with three simple outline targets representing a rock, paper and scissors, and a simple target dot for the fourth target.
A referee stands between two shooters who face their respective targets at a combat distance, which can be 1, 3 or 7 yards. The referee commands "threat" and shooters draw and fire on any of the three outline targets.
Shooters must assess each other's targets. Whoever "loses" the game must shoot the target dot of the "winner". The winner must also shoot his own target dot. Whoever shoots it first, wins.
A target-dot miss has to be corrected. The shooter must shoot his own rock, paper and scissors before shooting the correct target dot.
