We had a similar thing happen this past week at our local match. Two shooters needed to shoot though because they had to leave early. The first shooter walked up the line and started asking questions about the course, how many rounds, start position etc. The ro who was new was in the process of telling him to go read the wsb and the guy pulled his gun out of his holster. At no time was the guy given the make ready command.
The next shooter who was reading the wsb started asking what just happened and the ro started asking him does the shooter understand the course of fire.
I talked to the ro after he was finished and suggested not to engage with small talk before starting a shooter. If there’s a situation like that again tell him to read the wsb and call the next shooter up on deck. That leaves little to room for someone to do something stupid.
Yes the shooter who got dq’d was anxious to get started but wasn’t paying attention to what the ro was saying and he ended up going home. This immediately got his buddies attention and he had no issue understanding what he was supposed to do and not do.
The shooter that got dq’d went and complained to our rm that the ro didn’t used the proper range commands when he asked the ro about the course of fire.
