Airsoft games vary greatly in style and composition depending on location, budget, and the quantity of participants but often range from short-term skirmishes and organized scenarios to military simulations and historical reenactments.
Combat situations on the battlefield often involve the use of common military tactics to achieve the objectives set in each game. Participants typically use varying types of airsoft weaponry along with either real or replica military gear and uniforms.
Mil-sim is always Airsoft. Airsoft is not necessarily always mil-sim. Logical fallacies like this apparently make the world go round for some...
When people ask me what I do on the weekends, I tell them "airsoft". When they ask me that same question "You mean like paintball for panzies?" and start laughing, I laugh with them and then explain to them that I do Mil-sim, and what Mil-sim is. And the kind of airsoft guns that are typically found at a Mil-sim event. I have had several paintballers laugh at me because they think paintball is "more ****". Then they came to an airsoft game and got butt-hurt because a guy with a pistol killed both of them before they even got a shot off.
The TL;DR version: People who don't play airsoft know what "wal-mart" airsoft is. They'll never know what mil-sim is until they play it.
