The problem is I suspect that many of the players you are talking about are young people whose first introduction is via gaming.
If you are reared playing games like COD, your reality is warped.
When I was a child, many, many years ago, we would play war based on largely WW2 movies that we saw on TV.
We would run around a field or park with invisible guns making machine gun noises and if your mate didn't lay down when you shot him, you made damn sure he went down.
Now technology allows children to play with a variety of deadly weapons in gaming and kill hundreds at a time.
Is it any wonder, they take this attitude on to the Airsoft field.
Generally, Ive found young players to be pretty good but they really have no idea about fieldcraft, tactics, stealth and real life.
Why should they - they are 12 or whatever ?
They stand, talking loudly, usually next to where Im hiding and they generally enjoy themselves. The problem is when their behaviour starts to encroach on you enjoying yourself.
The answer ?
Either try to educate them by setting examples and explaining what they are doing is wrong or play somewhere else where there are less children.
Unfortunately, the site owners need their parents cash.
Are there any adult only sites ?
