Honestly, I decided to host a different type of training since it's rarely conducted. I explained how to properly place barriers on various types of roads, such as double-lane and single-lane roads. I also clarified which type of barrier should be used at the front of a roadblock. After that, I asked each participant, one by one, to assist in placing the barriers. I then deployed the road blockade near a route commonly used during armed robberies, aiming to intercept suspects or catch those attempting to escape, and indeed, we successfully eliminated a few criminals.
