CQB Airsoft vs Woodland: Types of UK Site Explained

CQB airsoft - close quarters battle - is short-range play in and around buildings, either in an indoor arena or in a built-up outdoor area. Woodland airsoft is played outdoors at longer ranges. Milsim is a type of event, not a type of ground. Of the 43 UK fields we checked, 8 are indoor CQB, 13 are woodland and 10 have both.

This article covers what distinguishes each type, how the rules change between them, and what milsim involves. New to airsoft? Our guide to what airsoft is covers what to expect on a game day.

What is CQB airsoft?

CQB stands for close quarters battle. At a CQB airsoft site, most of the play happens at short range inside buildings - corridors, rooms and tight spaces - rather than across open ground. Of the 43 sites we checked, 8 are indoor arenas, one describes itself as CQB without naming whether it is indoors, and two are outdoor urban sites where the buildings sit in the open air (South Coast CQB and Ironsight).

Indoor arenas vary in size. District 23 covers 17,000 sq ft inside a purpose-built American Midtown-style set. Tac House Spartan fills a 100,000 sq ft former tooling factory. Seven of the 8 sell sessions rather than a full game day; where the length is stated it runs from 1 to 4 hours.

Short ranges mean fast, frequent engagements. None of the indoor arenas we read sets a minimum engagement distance for rifles. At close range, hits feel different from outdoor play - our guide to does airsoft hurt covers what to expect from a short-range shot.

Only The Mill in Northern Ireland and Scorpion market themselves as all-weather on the pages we read.

Rules you'll meet at CQB sites

The biggest rule shift from outdoor play is fire mode. Thirteen of the 43 sites state a semi or single-shot rule because the site is CQB or because of its buildings. Six apply it across the whole site, and only Ironsight gives the reason on its rules page: "We are a CQB site so semi only."

None of the 8 indoor arenas has a DMR or sniper class. The Vault's indoor power table marks both as "N/A". CQB Arena recommends that all players wear full face protection inside the arena.

Three CQB sites cap BBs at 0.25g - Biohazard, Siege and The Vault. Four indoor arenas set a lower HPA limit than the standard AEG ceiling. Three CQB arenas ban pyrotechnics or smoke entirely; smoke is banned inside buildings at 8 of the 43 sites. Two sites - South Coast and Scorpion - recommend ear protection because of indoor noise.

Our FPS limits guide covers the indoor power figures and what no DMR class means in practice. Airsoft safety rules covers the wider rule picture for each site type.

What is woodland airsoft?

Woodland airsoft is played outdoors on natural terrain - trees, undergrowth and open ground. Thirteen of the 43 sites we checked are primarily woodland, from 15 acres at AIM Swindon and HQ Airsoft to 300 acres at Cotswold Airsoft. Woodland sites run a full game day, with several rounds and breaks across it.

Longer outdoor ranges make sniper and DMR (designated marksman rifle) classes relevant here in a way they are not indoors. Both carry minimum engagement distances at most outdoor sites. Our FPS limits guide covers the typical distances and what a player inside them needs to do.

What woodland means for your kit

Eight of the 43 sites give terrain as the specific reason for recommending boots - slopes, uneven ground and boggy sections. Nineteen of the 43 recommend or require boots for any reason. S51 puts it plainly: "We strongly recommend sturdy boots and gloves for the forest terrain."

Mud is a regular feature. Nine sites mention it and suggest a change of clothes. Sixmil's safety brief includes a line worth knowing: "Footwear can also be lost in these boggy areas if entered." Players of War gives the standard woodland caveat: "We can't promise you won't get wet and muddy though."

Mixed sites, quarries and other ground

Ten of the 43 sites mix woodland with a named built-up area - a village, town, CQB zone or structures set into the outdoor ground. Examples: Players of War runs 65 acres of plantation forest with a town, church and train station; Cotswold adds a village to 300 acres of woodland; Ultimate Wargames has three areas including two CQB compounds and a town; OP-Tac covers over 200 acres of quarry, woodland and multi-level purpose-built structures.

Where mixed sites include buildings, the rules change inside them. Seven of the mixed and other sites in the set apply semi or single-shot rules inside structures. Sixmil, and OP-Tac at its events, apply semi-only within about 5 m of a building.

The other five sit outside standard categories: Humber Airsoft and Revolution play in quarries; Blackout Airsoft Cornwall runs inside two miles of mine tunnels plus surrounding quarry and woodland, with helmets and torches required in the tunnels and no DMRs or snipers allowed inside; Commando Force runs a 10 m x 5 m indoor CQB zone (its Drakes Island games are suspended until 2027); and Black Ops Bristol plays in and around a former British Army base. Each has terrain-specific rules - read the site's own rules page before you book.

What is milsim?

Milsim is a type of event, not a type of ground. Seventeen of the 43 fields run milsim, battlesim or similar long-format events. The same woodland, quarry or mixed sites that host ordinary skirmish days run these events - no site type has milsim to itself.

Durations range from 8 hours (OP-Tac's battlesim format) and 12 hours (S51's Tarkov event) to 24-hour operations (Gunman's Descent, OP-Tac's milsim) and full weekends (Tactical Delta, Gunman filmsim weekends). Nine of the 43 offer camping alongside their events. At OP-Tac's 24-hour milsim, players sleep in the game zone and are still in play: "You are still in play while sleeping; you must wear your eye/face protection as you can be captured by the enemy team."

Milsim events add set roles, command structures and limited respawns or medic rules. Three require uniform or faction-specific camouflage. Four limit the type or quantity of ammo players can carry.

The terms are used loosely. OP-Tac describes a battlesim as the step between a skirmish day and a full milsim: "A great stepping stone is a BattleSim, our shorter, scenario-driven game that sits between a skirmish and a full milsim." One S51 event is labelled both "12hr Battlesim" and "12 hr (Milsim)" on different pages of the same site. No indoor arena publishes a milsim or battlesim event with detail.

Can beginners go to a milsim?

That depends on the event. Three fields set a higher minimum age for these events than for a normal game day: OP-Tac requires participants to be at least 16 for its milsim (versus 11 for its battlesim); S51's Tarkov event states "18 years plus recommended, Or parental consent applied, must have Airsoft experience"; Tactical Delta notes that certain events may be restricted to participants aged 18 or over.

Kit rules get stricter. OP-Tac's milsim requires correct team camouflage or players may be reallocated; boots are required and trainers are not permitted. S51 specifies faction headgear and weapons for each faction. Gunman's Descent event caps magazine loads at real-steel capacity plus 5 rounds.

Read the event pack in full before you book. Ask the organiser directly if anything is unclear - event rules change between runs, and the field is the authority on its own events.

Night games at every type of site

Fifteen of the 43 sites run night or dark games, across every terrain type.

At indoor arenas, night play means the lights go off on purpose. Siege: "Every Thursday night at The Siege Project, we go from lights-on tactical engagements to full blackout battles." The Vault runs night-vision-only phases and includes night-vision equipment in its hire kit for those sessions.

In woodland the trees stay unlit. CAG (Combat Action Games) says what to expect on its night raid page: "Our Dusk games are only ever single fire events also we don't light the woods so please bring some form of torch." At NML, players choose their own light level - certain areas can be lit, but complete darkness is also available.

Night games frequently carry their own rules around fire mode, torches and lasers. Our airsoft safety rules guide covers the common restrictions that apply after dark.

CQB or woodland: which to try first

Neither type is better for every player. The table below covers the main practical differences, based on what the fields' own pages say.

Most sites of both types hire out airsoft guns and face protection, so you don't need your own kit for a first game. Ask the site what its hire package includes before you book.
