Quick Answer

Is Hereford Base worth learning in R6 in 2026?

Yes, but treat it as a legacy and training map, not as a modern ranked staple. Ubisoft still has an official Hereford Base map page that lists the United Kingdom location, the base-game release and the September 2018 rework. Ubisoft’s Year 10 roadmap also listed Hereford Base among maps added to the Map Training playlist. That makes it worth learning for customs, training, casual knowledge and players who want to understand Siege’s older map language.

Hereford is especially useful for learning floor-first communication. The rework expanded floors, added more movement between levels and made room identity more distinct. If you only call “upstairs” or “basement,” your team gets very little. If you call “3F Tractor,” “2F Kids,” “1F Dining” or “B Fermentation,” teammates can actually aim the right angle.

Clean takeaway

Do not learn Hereford as a ranked formula. Learn it as a stacked-building callout drill: floor, room, stair, hatch, then side of pressure.

Map Overview

What makes Hereford Base different?

Hereford Base is one of Siege’s oldest names. The official Ubisoft description frames it as the SAS training ground, full of plywood targets, sandbags, barbed wire and obstacles. The rework arrived in September 2018 and changed the map dramatically: larger floor surfaces, new stairs, more movement between floors, stronger room identity and more destructible play. It still feels like a training facility, but it no longer plays like the original killhouse.

That history matters for SEO and for real players. Some people search for old Hereford memories, some search for the rework, and some only need callouts for Map Training or customs. This guide focuses on the reworked layout’s practical room names and bomb sites, because those are the names that help you communicate today.

Callout Basics

Core Hereford callouts every player should know

Start with the four bomb pairs. Hereford’s reworked bomb sites are 3F Ammo Storage and 3F Tractor Storage, 2F Kids Bedroom and 2F Master Bedroom, 1F Kitchen and 1F Dining Room, and B Brewery and B Fermentation Chamber. Once those are memorized, add connector names like Attic, Piano, Barrel, Workshop, stairs, hatches and the spawn references Control Tower, Spitfire Courtyard and Shooting Range.

The biggest mistake is using old or vague language. Hereford has a lot of nostalgia around the original version, but a teammate in a current custom or Map Training session needs the room they are actually looking at. Keep it practical. Call the floor, room, and direction of movement.

Bomb Site

3F Ammo Storage and 3F Tractor Storage callouts

Ammo and Tractor is the top-floor Hereford site and the one most associated with the rework’s vertical identity. The area is strange because the third floor contains limited true room space and a larger Attic-style connector. That means attackers and defenders should avoid lazy “top floor” calls. Top floor can mean Ammo, Tractor, Attic, stairs, hatch pressure or a rotate between those spaces.

Attackers should clear top floor with drones and stair pressure rather than walking into unknown close angles. Defenders should use the site to waste time, not die early in a hero swing. Because the room pool is compact, a single trap or shield can slow attackers, but once attackers know the exact defender position, there are not endless places to hide.

TeamPriority calloutsPlan
Attack3F Ammo, 3F Tractor, Attic, top stairs, hatchDrone the first pocket, control one stair, then pinch site from Attic and room door.
DefenseAmmo door, Tractor cross, Attic pressure, stair soundUse traps and crossfires to slow attackers before they own top floor.
PlantAmmo plant, Tractor cover, Attic flankPlant after the stair and close corner are confirmed, not before.
Top-floor mistake

Do not say “top” and stop talking. Hereford’s third floor needs the actual room name because Ammo, Tractor and Attic all create different fights.

Bomb Site

2F Kids Bedroom and 2F Master Bedroom callouts

Kids and Master is easier to understand than the top floor, but it still punishes vague communication. Attackers need to know whether a defender is in Kids, Master, hallway, stairs or behind a shield/soft line connecting the rooms. Defenders want attackers to walk into a bedroom fight without checking the adjacent room first.

This site is good for learning standard Siege room-clearing language. Call the room, then the side. “2F Kids, door side” is useful. “2F Master, deep corner” is useful. “Bedroom” is not enough because the site has two. If a defender rotates between Kids and Master, update the call immediately so your teammate does not pre-aim an empty corner.

1
Separate Kids from MasterDo not call both rooms “bedroom.” Hereford’s 2F site needs exact room names.
2
Own a stair before executeStairs let defenders collapse or escape, so attackers should control at least one vertical path.
3
Drone the connector and cornersSmall bedroom sites reward close defenders, traps and shotgun pressure.
4
Use utility to break the first holdFlashes, soft breach, vertical pressure and shields are better than dry swinging blind.
5
Watch the rotate after first pickHereford defenders can slip through the floor chain if attackers celebrate too early.
Bomb Site

1F Kitchen and 1F Dining Room callouts

Kitchen and Dining is a classic mid-floor objective pair. It teaches two things at once: first-floor room control and vertical pressure from above or below. Attackers should not treat the site as a simple doorway execute. If defenders have traps, shields, gas or a protected crossfire, a single-lane push gets stalled fast. The better plan is to clear enough surrounding space to attack Kitchen and Dining from more than one angle.

Defenders can build this site around denial and information. Smoke can delay a plant route, Castle or Azami can shape doors, Mute can protect from drones, and Valkyrie or Maestro can call the exact timing. Attackers should call whether defenders are Kitchen side, Dining side, Piano side, stairs side or playing below for C4. That context decides whether the team uses vertical play, hard pressure or a rotate.

Bomb Site

B Brewery and B Fermentation Chamber callouts

Brewery and Fermentation are the basement bomb rooms and the best place to practice calm lower-floor calls. Basement callouts should always start with “B” or “basement” because many Hereford room names sound like storage or utility rooms that could exist elsewhere. Say “B Brewery,” “B Fermentation,” “B Barrel,” “B Workshop” or “B stairs” so teammates know the layer instantly.

Basement attacks need map control before plant pressure. If defenders own the stairs and nearby rooms, attackers get trapped at a door. If attackers clear the stair route, drone the site and pressure two sides, defenders lose the comfort of a single crossfire. Basement defenses should avoid all sitting deep in site with no information. Hold a stair, a nearby room or a camera line so the team knows when the execute starts.

Attack priorityControl basement stairs

Stairs decide whether defenders can swing, rotate or deny the plant late.

Attack priorityClear Barrel and Workshop

Support rooms can hide defenders who punish site pressure from the side.

Defense priorityDelay first entry

Use wire, traps, gas, C4 and information to make attackers spend time before site.

Defense priorityKeep a retake route

A basement defense with no rotate or stair control collapses once the first anchor dies.

Basement rule

Call basement rooms with the floor prefix every time. “Fermentation” is good; “B Fermentation, stairs side” is much better.

Attack Routes

How to attack Hereford Base

Hereford attacks are easiest when the team chooses a floor chain. Because the map is stacked, attackers can waste a lot of time clearing the wrong level. Decide whether the round needs top-down pressure, direct site pressure or basement/stair control. Then pick the spawn that supports that route: Control Tower, Spitfire Courtyard or Shooting Range.

1
Choose a first floor to ownDo not enter randomly. Pick top, second, first or basement control based on the site.
2
Drone the first stair and connectorRoamers and traps are strongest when attackers assume a stair is clear.
3
Use vertical play with purposeBuck, Sledge and Ram should open for plant denial, utility clear or defender displacement.
4
Cut rotations after first pressureOnce a defender leaves site, hold the stair or hallway that lets them reset.
5
Plant only after the support room is called clearHereford has many side rooms that punish a plant if attackers focus only on bomb room names.
6
Keep calls short and layered“2F Master stairs” beats a long story about where someone might have gone.
Defense Setups

How to defend Hereford Base

Defending Hereford is about stair control, vertical denial and information. The rework added stronger movement between floors, which means defenders should not hide five players in the same objective room. Use a shallow roam, a camera, a trap route or a protected stair position to slow the attack before it reaches the bomb site.

The strongest defender lineups on Hereford usually include at least one setup operator, one anti-projectile operator, one information operator and one delay operator. You want attackers to spend time clearing stairs and utility before they even touch site. If the team dies early in isolated rooms, the map’s stacked structure stops helping and starts hurting.

Operator Picks

Best operators for Hereford Base

Hereford rewards operators who understand layered map control. Attackers need information, vertical pressure, flank control and enough breach utility to open the rooms that matter. Defenders need trap routes, anti-drone tools, protected anchors and enough delay to force attackers into bad late-round choices.
