If you can take a backup rifle with you, then bring it. “Backups for everything” is a good rule to follow for milsim.

Bring a tool kit as well. During your rest periods, you can fix whatever’s wrong with your gear.


It’s best if you can take at least 5 magazines and maybe a 400-round speed loader. About a thousand rounds should be fine.

If you can, bring a backup facemask as well. If a set of goggles crack and you don’t have a spare, you won’t be able to return to the fight.


This is crucial for nighttime operations, and it’s affordable.

Some do use night-vision goggles, but such things may be too expensive.

However, if you have night-vision goggles then you can see in the dark without revealing your position to your opponents.

However, week-long events are virtually impossible to host, since most airsoft fans don’t really have that much time to spare. Also, injuries can become more likely the longer the milsim operations goes.

There was a 9-day Eastwind event, though. The event emphasized realism, so contact was actually rare.
