Airsoft
I have seen the stuff since the beginning when it was introduced to North America.
And why the hell do you need a combat knife on an airsoft field????
2 WORDS PRUNING SHEARS...lol

that wil do the job.
I was playing paintball in Toronto Canada @ Skyball.. Immediately I thought it was a bad idea to promote faux small arms that can be mistaken for real weapons. .I mean an officer would NOT be able to tell the difference if a young kid pointed it in his/her direction there could be an incident.
Also at the time there was a huge controversy with even paintball guns being toted by immature children creating mischief and vandalizing private/public property. Just not a good idea.
I have handled the real deal ...you name it Sig,1911s, M4, MP5, M16, M14, M60, M1 Uzi, AK-47..Etc you cannot tell the difference that its an airsoft gun!! Lets face it kids will be kids and all you need is a magic marker to cover up the SAFTY ORANGE tip.
And as a licensed concealed carry pistol permit holder here in N.Y. if anyone pointed an airsoft at me there is going to be an incident. You just cant distinguish real from faux.
I have PLAYED ONE and help coordinate several of the WEST POINT "Big Games"....and I guess since I have been in actual combat I just dont get it.
If the people that participate in Paintball "Woods Ball" and especially Airsoft knew what actual Operators, Military Personnel and Combat Veterans thought of the whole civilian war game thing these "woods ball" and Airsoft players would be embarrassed to the point that the smart ones would hang it up.
So... anyway to make a long story short as an avid shooter, NRA Life member, and EX-amateur Paintballer its my opinion Stick to Paintball (speedball) get some exercise by running the bunkers... War isnt fun it is just glorified by Hollywood and these Airsoft fields to name a few.
Airsoft should be kept in Japan where it originated from where they cant own the firearms that we can. Why dont you try spending your $$ on some real firearms those airsoft gun can get up there in price. Buy the real deal AND
Keep "AIRSOFT" to the "AMERICAN WANT TO BE" Japanese.
