Airsoft BattleSim Rules

Our BattleSim Rules are designed to make sure you get the most out of the event you are attending. They’re not too strict like our Immersive MilSim rules, but carry enough structure within them to ensure a smooth running day, with just the right amount of challenges within allowing you to get the best of both a more casual game, as well as getting a more structured, military style event.

Remember though, these are not what we call MilSims. They are BattleSims and are a half way between a MilSim and a Skirmish.

When arriving at one of our BattleSim Events, it is important to take due care, for your own safety, particularly for events being held at Military training areas.

With this in mind, ALL players are advised not to arrive to site in full military clothing, and are recommended to arrive in civilian clothing, or a mix of, and get changed once on site.

Gate’s WILL close at 08:45 sharp with the aim to carry out a safety brief by 09:30, in time for a 10:00 game start. Late arrivals delay the game for everyone else, so we will close the gate at that time, and while we will accommodate genuine late arrivals as best we can, it is not always possible to get you on once the gates are closed. In short, DON’T BE LATE.

The event will generally finish no later than 16:00 on the same day, unless otherwise stated.

You MUST bring all food and water that you require for the event with you. We have light snacks and drinks available for sale on site, but we do not provide food. You must self administrate, in the field, throughout this event.

Please note the following recent rule changes;

  • Multicam Tropic is now banned as a uniform choice due to multiple complaints of confusion over multiple events.
  • Shoulder fired mortar systems using TLSFX or similar cardboard mortar rounds are banned due to player misuse.
  • Master Mike, Mini Mike and similar bb shell launchers are banned as they do not fall within the nature of our events.
  • Military smokes (including those re-purposed and bought through airsoft companies) are banned due to safety issues (Enola Gaye Mil-X and similar from other manufacturers ARE allowed).

Additional COVID-19 Rules:

  • All players are responsible for their own transport to and from site under government guidelines. Players should avoid car sharing where possible
  • Hand sanitiser will be made available to all players and should be used upon arrival.
  • Players are to remain at their vehicles and are to prep their kit and equipment there.
  • All players to keep a distance of at least 2 metres apart while at the event.
  • A minor safety brief will be given on the day to confirm rules of the event.
  • All buildings in play at Longmoor are deemed as open air buildings, and such can be entered without face coverings. However, players must ensure that no more than 3 players enter any 1 room, at any times and must always ensure as best they can to keep a 2 metre social distance.
  • Absolutely no searching of enemy players, or contact of any kind (i.e knife kills) is to be carried out at this event.
  • There will be a small shop on site selling pyro, ammo and tactical kit.

Ammo Limits and FPS Limits:


All FPS limits are on a 0.2g bb. Ammo limits are per person, on your person, at any one time. You may have as much ammo in your regen area as you like, but no more than the designated ammo limit, inside magazines, on your person at any one time.

TAG Rounds have a minimum engagement distance of 40 metres. Within this MED TAG rounds are NOT to be used. TAG users MUST make themselves known at the start of the day and attend a separate safety brief.

ALL GUNS MUST BE CHRONO’D AT THE DESIGNATED CHRONOGRAPH ONSITE.Random spot checks may also be carried out throughout the day.

Any HPA guns MUST have a tournament lock with a rate of fire no higher than 25rps. Trigger spamming will NOT be tolerated.

Semi fire ONLY while inside buildings. Full auto fire is allowed into and out of buildings: players will be expected to fire short controlled bursts and be aware of their surroundings to prevent overkill of players crossing open windows/doorways.

Cracks in doorways, under doorways or any hole that is not big enough to obtain a full site picture, MUST not be engaged through. Generally speaking, if it is smaller than a piece of A4 paper, you MUST NOT engage through it.

All weapons MUST have a realistic rate of fire.
Any weapon that doesn’t obviously fall into the above categories, please contact us for further info.

No loose ammo is allowed to be carried on your person and magazines and Moscarts must only be reloaded in designated aid posts/regen areas.

BFG’s & Pyrotechnics:

Pyrotechnic products are allowed to be used on site, but nothing above a Mk5.

Any form of blank rounds for Blank Firing Grenades can be used up to and including 9mm. NOTHING above 9mm is to be used in BFG devices.

There is no limit to the amount of pyro you carry.

BFG’s can only be reclaimed once the area is clear of combat OR, if your whole team is dead, you may ask the enemy team to retrieve and hand back your grenade to you, although this is not a given, so do not be surprised if they decline. 

No over arm throwing of BFG’s are allowed. Posting of grenades IS allowed in a controlled manor, and you must use them in a sensible manner.

Military Smoke is NOT allowed at these events.

Player Engagements:

We DO NOT operate a “bang” rule at our events, although we do insist on sensible game play, and will remove players who are intentionally trying to hurt other players.

Players must use Single Shot fire only, while engaging enemy players inside the same building they are occupying,

Full auto fire may be fired out of buildings, and into other buildings.


You assault a building and use full auto fire to suppress the windows and firing positions. Upon entering the building you switch to single shot to engage enemy players inside the building. Once you have cleared the building, your team mates decide to assault the building across the street. You may now switch to full auto and fire out of your building, and into the building across the road.

TAG Rounds:

Tag rounds and their launchers may be used in this game. If you are planning on bringing a TAG launcher and rounds to the event you MUST inform us before hand. ANYONE using TAG launchers and rounds in a way that we deem unacceptable and/or unsafe or not within the spirit of the day will be removed from the site immediately with NO REFUND.

You must use TAG launchers as area weapons, and not as direct impact weapons. That means do NOT intentionally try to hit individual players.

A high arc of fire must be used to lob the round onto target.

You may fire TAG rounds into buildings

4Om Minimum Engagement distance applies at all times.

Medic Rule:

All players must carry their own dressing on their person (Supplied by you). No dressing, no medic.

You may only carry one dressing on your person (apart from designated team medics). Groups of players may form a team and nominate a team medic to carry further bandages (Supplied by you).

You are hit when a bb strikes your body or slung/holstered weapons. Strikes to your “in use” weapon system do not count. When players are hit they must kneel, or lay down and immediately shout hit, using a red dead rag if you have one (these will be available from our store on the day).

Wounded players must ONLY be moved by carrying or dragging.
Wounded players must ONLY be moved by carrying or dragging.

If you do not wish to be dragged or carried, then you must wait until your team can push past you and medic you in place, or until you bleed out.

  • First Hit = Any player can use YOUR own bandage to revive you.
  • Second Hit = Only a team medic (from any team) can revive you using one of their bandages.
  • Third hit = You are DEAD and must return to your Regen after your 5 minute bleed out.


If you are not treated within 5 minutes of being hit, you have bled out and must return to your regen.

You MUST wait 5 minutes to bleed out. Players cannot instantly walk off when they are hit, no matter how they are killed. Once you are dead you MUST still bleed out for 5 minutes. That means 5 minute bleed out from both grenades and bb strikes.

Grenade and TAG rounds have a 5-metre kill radius and are an instant kill, even IF you are already waiting for a medic, and remember, you still require a 5 minute bleed out from this.

Dead players don’t talk, and we recommend the use of dead rags, although these are not compulsory.

Minimum age limit for our BattleSim events is 16 years old.

Any players not adhering to these rules, which WILL be sent to you separately, may be expelled from the event with no refund given.
