MilSimUSA Ruleset

First & Foremost

1. ALL PLAYERS ARE REQUIRED to have a signed liability waiver to play at any MilSimUSA event. Players under the age of 18 will need a parent or legal guardian to sign on their behalf. The waiver will vary depending on the AO that the event is held at. You can find a waiver for Quail Run here and one for Flat Acres Farm here.

2. ALL PLAYERS ARE REQUIRED to wear full sealing ANSI Z87.1+ rated goggles, or paintball mask or better (This is usually posted on the product manufacturing or the company website.) Eye protection must be worn at all times while outside the staging area. NO safety glasses, shooting glasses or ski goggles will be allowed onto the field. This rule is the single most important rule that we have and we enforce it very strictly.

– You will not be allowed to play without the above 2 items. NO EXCEPTIONS.


Pre-Game Rules

– Please bring all of your gear to the event in a Gun Bag/Case or some other means of covering up your gun(s). We do this to further establish airsoft/milsim as a responsible sport.

– While in the staging area pistols must be holstered. All other weapons must have the magazine removed and the chamber cleared. After games eye protection may only be removed after all players have mags out, chamber cleared and game control has given the okay to remove goggles. Players found with a mag in their gun will be instructed to remove it unless we are “Goggles on”.

– While in the parking lot area you must keep your guns in a gun bag or case. You may only use the designated staging area to dry fire your weapon to ensure it is working properly. There is to be no live fire anywhere within the staging area other than the chronograph station, target shooting and/or the test-fire station. This area will be designated by staff.

– ABSOLUTELY NO SHOOTING in any parking lots at MilSimUSA events.

– Do not take/touch other’s personal gear.

– Refrain from wearing vulgar or obscene patches, swag or apparel. (Be mindful that we are often in the presence of minors.)

Gameplay Rules

– DO NOT for any reason remove eye protection, unless you have exited the field and are in the staging area/parking lot.

– Vulgar, crude, or disrespectful language will not be tolerated. It may result in game expulsion.

– ALL PLAYERS ARE REQUIRED to have a BRIGHT RED “Dead Rag” minimum 50 square inches of material and/or a RED Chem light for night games. A standard red bandana can be purchased for $0.99 at Hobby Lobby and MilSimUSA will always supply red chem lights for any night games that we host.

– All airsoft guns/weapons and/or BBs are subject to inspection by any member of staff if we feel that your gun is shooting too “hot” (the muzzle velocity is too high) or it poses a safety issue to the event. Note that any and all players may be asked to chronograph at any time during the day or night, including during play. Players caught caught shooting too hot more than once may be removed from the game.

– Players will only be allowed to use airsoft specific guns. No “BB Guns” or BB guns converted to use airsoft BB’s or Metal BB’s will be allowed.

– Bio Ammo only, no metallic or paint BBs

– Any hit that does not strike the player’s primary weapon (note: the primary weapon may not be used as a shield or a bat to prevent hits) shall count as a hit.  This include boot hits, finger hits, Friendly fire always counts.

– Once a player is hit, they are to yell HIT! Place their dead rag on their head and move to either the nearest re-spawn or they are to remove themselves from the field of play.

-In addition to wearing your Dead Rag a player should assume a neutral non-threatening posture.

-Dead men do not talk! Period. This includes radios.

-Dead men do not shoot! This confuses and irritates the active players and breaks down the quality of the game.

– On the call of “BLIND MAN!” or “REAL WORLD”, all players need to stand in your location and do not move until the “all clear” and “game on” is given. Only at that time may you continue play.

– Call out “Real World” if you or another player is injured and requires immediate Admin/Medical attention. This is to communicate that their is a real world problem that needs to be dealt with. You will need to both vocally and via Comms make the “real world” call.

– Call out “Blind Man” if a player loses their eye protection (falls off, broken lens, broken strap, etc) during a fire fight. The player needs to cover their face with their hands and keep their head down until eye protection can be provided for them or are ushered off of the playing field.

– No Blind Firing. Player must be able to see your target and your front sight post.



– We do not recognize any form of Bang Bang kill, trigger kill, safety kill or any such thing. The only way that another player may be eliminated at our games is with a BB fired from a gun, a BB from a grenade “explosion” or a melee kill with a MSU approved melee weapon. That is all. Do not come to game control talking about a bang bang kills. We will tell you that no such thing is recognized at our events.

Rubber Edge Weapons and “Tap” kills.

– Players are allowed to “melee” or “Tap out” another player with rubber edged weapons and plastic ColdSteel training knives.

– When a player is touched/tapped with themelee weapon they are considered “hit”.

– Player that have been “killed” by a melee weapon cannot yell “hit” or “medic” they are mortally wounded and must remain silent. It’s often a lot of work to get melee kills so we like to reward those who mange to pull it off.

All melee kills are instant kills with no bleed out. Go back to respawn immediately.

– Only MilSimUSA approved training weapons are allowed.

– No modified “real edged” weapons are allowed.

– No aggressive physical contact is allowed. Any overly aggressive play will result in expulsion from the game



Players carrying Mid-Cap mags and/or Low-Cap mags are may carry an unlimited number of magazines.

Players using Hi-Cap magazines/Winding Magazines may carry a maximum of 1 Hi-cap magazine.

NOTE: Hi-Cap magazines have been given the nickname “bitch buckets” by the MilSim community across the United States. We are not a fan of Hi-Caps but we allow the use of 1 Hi-Cap to allow newer players to attend before they have any of their Mid-Caps built up. These are allowed but we make fun of Hi-Caps because we think they lower the level of game play and experience for all. MidCaps make for a much better player and community.

Support weapon gunners will be allowed a maximum of 2 box magazines.

Box/drum/C-Mags are only allowed to be used with support weapons.

Sportsmanship is expected! Please call YOUR OWN hits!


Not calling your hits is cheating, and will not be tolerated, period.

If you suspect a player is not calling their hits, do not take matters into your own hands. Please bring this to the attention of your SQL and the event staff, use the chain of command.

Dead players do not talk! Dead players may only talk quietly to other dead players. Dead players do not shoot their guns, doing so immediately makes you a live target. Dead players do not improve their position, or indicate other players position while dead.

Electronic warfare: jamming or listening in the opposition’s radio frequency is strictly prohibited (unless cleared by the administration).

Blind fire: Shooting around corners and not being able to see where your BBs are going is not allowed.

Airsoft is about HONOR, failure to play in an honorable manner will result in expulsion from the event. There will be no bullying, rough housing, foul language (used in malice), or physical/mental intimidation anywhere at anytime at a MilsimUSA event. Failure to follow these rules will result in expulsion from the event and AO no refunds will be given.



– When a player is hit they may vocally or via radio call for a medic that will attempt to revive them.

– Once a player is hit they must sit, kneel or lie down, a medic has five minutes to reach them in order to treat a wounded player before they “bleed out”. Players have the option to waiting for a medic or instantly going back to respawn.

– Once a player has “bled out” they must then re-spawn at their nearest MASH Unit or FOB.

*Squad leaders should be knowledgeable enough to understand when their squad is combat ineffective and  re-spawn his/her entire squad — 70% casualty rate is the magic number.



– Each squad may be assigned a medic. (Subject to change with various Teams and Squads)

– Each medic may be given a medic’s bag with up to 6 bandages.

– A medic will treat a fellow player by going up to that player and bandaging the area where the player was hit

– A player may only be treated by a medic twice before they must go respawn without any bleed out.

– Medics CAN NOT re-use bandages from “dead” players. When the medic has exhausted their six bandages they will need to visit a MASH unit or FOB to re-supply.

– Medics many never have more than 6 bandages at any one time

– Players inside structures MAY NOT BE TREATED by a medic. If you are hit within a structure you are considered KIA and must exit the building go respawn.

– Scenario and Admin vehicles are limited to 25 MPH

– Players are not allowed to exit or enter a moving APC(s)

– Players are never to stand , lay prone or supine next to any roads and/or a moving APC(s)/Tanks because of the turn radius blind spots.

– Player should exercise EXTREME caution around APC(s)/Tank doors and hatches.They are heavy and will easily “remove” fingers.

– Only shoulder launched rockets disable armor (APC, Tanks) Must be a frontal hit (for the driver to see) this does not kill the crew, but only disables the APC/Tank and forces the crew to exit.

– 40MM/Rocket hit only disable un-armored vehicles. Direct hit to the cab disables the vehicle and kills all in the front cab. Players in the troop area are combat effective and must exit the vehicle.

– 40MM/Rocket hit inside the “storage or troop area” disables vehicle and kills all player inside the vehicle.

– Players shot inside a vehicle are to  follow the normal medic and re-spawn rules.
