SMGs define the tempo of every fight in Battlefield REDSEC. Their mobility, blistering fire rate, and hip-fire accuracy make them the best tools for clearing buildings, holding choke points, and bailing out teammates at point-blank range. This guide ranks every SMG from S to C Tier in REDSEC and breaks down the best loadout and usage tips for each one so you always know which gun to bring into the warzone.
1. Battlefield REDSEC SMG Tier List
This tier list ranks every SMG in Battlefield REDSEC based on time-to-kill, recoil control, magazine reliability, and overall consistency in the current meta.
| Tier | Weapons |
|---|---|
| S-Tier | SGX, UMG-40 |

| B-Tier | PW7A2, USG-90 |
| C-Tier | SL9, KV9 |
2. S-Tier SMGs
S-Tier SMGs are the meta-defining guns in REDSEC. They combine lethal close-range damage with controllable recoil and flexible attachment options, making them reliable picks for almost every squad composition and playstyle.
2.1 SGX
The SGX is the classic all-rounder SMG in REDSEC. As the default SMG, it’s incredibly accessible yet remains competitive even in high-level lobbies. With a forgiving recoil pattern, solid effective range for an SMG, and great hip-fire, it’s ideal for players who want a single gun that can comfortably handle both room clearing and mid-range duels.
SGX
SGX – Best REDSEC Loadout
- Optic: ROX 1.50x
- Muzzle: Flash Hider
- Barrel: 4.5″ Compact
- Underbarrel: Slim Angled
- Magazine: 30rnd Fast
- Top Accessory: 5 MW Red
- Ammunition: Hollow Point
Loadout Summary: This close-range build turns the SGX into a laser for tight gunfights. The 4.5″ Compact barrel and Slim Angled grip significantly improve hip-fire accuracy and ADS speed, while the Flash Hider hides muzzle flash and keeps your position less obvious in hectic fights. The 30rnd Fast magazine minimizes vulnerability between bursts, and Hollow Point plus the 5 MW Red laser make it easy to land lethal headshots at short range.
SGX – Tips & Usage
- Use the SGX for aggressive entry plays: slide into rooms, hip-fire at first contact, then swap to ADS once you stabilize.
- Take advantage of the Flash Hider to spam corners without instantly giving away your exact position.
- Fight around cover at 5–20 meters where your hip-fire and Hollow Point damage shine.
- Avoid overcommitting at long range—swap to a rifle or reposition instead of forcing fights beyond your effective distance.
2.2 UMG-40
The UMG-40 is the most dependable SMG in REDSEC thanks to its excellent recoil control, fast reloads, and strong performance from close to mid-range.
UMG-40
UMG-40 – Best REDSEC Loadout
- Optic: Mini Flex 1.00x
- Muzzle: Standard Suppressor
- Barrel: 200mm Custom H
- Underbarrel: Alloy Vertical
- Magazine: 30rnd Fast Mag
- Right Accessory: 5 MW Red
- Ammunition: Hollow Point
Loadout Summary: This build leans into the UMG-40’s natural precision. The Standard Suppressor keeps you off enemy compasses while the 200mm Custom H boosts bullet velocity and ADS speed so you can snap onto targets quickly. Alloy Vertical and the 30rnd Fast Mag stabilize your aim and ensure you are rarely caught mid-reload, while Hollow Point and the 5 MW Red laser reward accurate headshots and tight hip-fire tracking in tight spaces.
UMG-40 – Tips & Usage
- Play around close-to-mid sightlines rather than pure point-blank brawls; the UMG-40 farms players who overpeek at 10–30 meters.
- Use the Mini Flex 1.00x to pre-aim doorways and common peeks; your low recoil makes pre-firing very effective.
- Abuse the 30rnd Fast Mag to chain multiple enemies without fully disengaging—reload behind partial cover rather than retreating completely.
- Trust your beam: hold steady tracking instead of overflicking; the UMG-40 shines when you keep your aim smooth.
3. A-Tier SMGs
A-Tier SMGs are extremely strong weapons that can rival S-Tier picks with the right loadouts and player skill. They usually have one trade-off—such as mag size or handling—that keeps them just below the absolute top, but they’re still more than capable of carrying you through REDSEC matches.
3.1 PW5A3
The PW5A3 is a precision-focused SMG that rewards accuracy over spray-and-pray. Compared to the SGX, it offers a more manageable fire rate and controllable recoil, making it perfect for players who like to track targets cleanly instead of just dumping bullets.
PW5A3
PW5A3 – Best REDSEC Loadout
- Scope: Iron Sights
- Muzzle: Standard Suppressor
- Barrel: 245MM Custom
- Underbarrel: Ribbed Stubby
- Magazine: 40RND Magazine
- Ammunition: FMJ
Loadout Summary: This close-range setup focuses on staying mobile and consistent in sustained fights. The Standard Suppressor keeps your shots off the minimap, while the 245MM Custom adds extra punch and stability. Ribbed Stubby smooths your recoil for cleaner tracking, the 40RND Magazine gives plenty of bullets for extended engagements, and FMJ helps shred armored targets at short range.
PW5A3 – Tips & Usage
- Play tight angles and pre-aim head height; the PW5A3 rewards accurate first shots.
- Stick to short-to-mid corridors and avoid wide open-ground pushes where rifles have the advantage.
3.2 SCW-10
The SCW-10 is one of the most terrifying close-quarters weapons in Battlefield REDSEC. Its insanely fast time-to-kill makes it a monster inside buildings and tight choke points, but it’s held back by tiny magazine options and a focus on ultra-close fights. Built correctly, it melts anyone who dares peek you at arm’s length.
SCW-10
SCW-10 – Best REDSEC Loadout
- Optic: Mini Flex 1.00x
- Muzzle: Single-Port Brake
- Barrel: Light 6.8″ Fluted
- Magazine: 20 RND Magazine
- Accessory: 50MW Green
- Ammunition: Hollow Point
Loadout Summary: This build is all about sheer close-range lethality. The Single-Port Brake reins in just enough recoil to keep your burst on target, while the Light 6.8″ Fluted barrel improves ADS speed and accuracy while moving. The 20 RND Magazine fixes the worst of the default mag size issue and the 50MW Green accessory plus Hollow Point turn any clean headshot string into instant deletes.
SCW-10 – Tips & Usage
- Think of the SCW-10 as a hit-and-run SMG: swing, erase, break line of sight, reload, repeat.
- Avoid challenging more than two enemies without hard cover nearby—your 20-round mag can’t sustain sloppy sprays.
- Use the high rate of fire to combo headshots at 5–10 meters where recoil isn’t yet a problem.
- Stick to interiors, stairwells, and container stacks instead of long street fights.
4. B-Tier SMGs
B-Tier SMGs are strong but more situational. They usually require better positioning, specific playstyles, or a bit more mechanical skill to match the output of S- and A-Tier picks. In the right hands and setups, they can still absolutely carry games.
4.1 PW7A2
The PW7A2 is an accuracy-focused SMG with extremely low recoil and smooth handling. It doesn’t hit as hard as the top-tier guns, but its laser-like control and reliable mobility make it feel incredibly consistent and forgiving, especially if you’re landing headshots.
PW7A2
PW7A2 – Best REDSEC Loadout
- Optic: Mini Flex 1.00x
- Muzzle: Single-Port Brake
- Barrel: Basic 180mm Standard
- Underbarrel: Slim Angled
- Magazine: 30RND Magazine
- Accessory: 120MW Blue
- Ammunition: Hollow Point
Loadout Summary: Since the PW7A2 already has incredible base recoil control, this build keeps attachments lean and efficient. The Single-Port Brake and Slim Angled give a light touch of recoil reduction and faster ADS, while the default Basic 180mm Standard barrel preserves snappy handling. Hollow Point compensates for lower per-bullet damage by buffing headshots, and the 120MW Blue laser makes close duels easier to win without overspending on handling upgrades.
PW7A2 – Tips & Usage
- Lean into precision and strafing: hold tight crosshairs and strafe to make yourself harder to hit.
- Use the PW7A2 as a bridge between SMG and carbine, comfortably taking fights out to mid-range if needed.
- If you struggle with ammo, consider swapping Hollow Point or your accessory for a larger magazine at the cost of some mobility.
- Perfect for players who enjoy recoil-free beams and consistent tracking rather than raw DPS.
4.2 USG-90
The USG-90 is the pure spray-and-pray SMG of REDSEC. With its extremely high rate of fire and big 50-round magazine, it can overwhelm full-armor targets in tight rooms. The price you pay is weaker per-bullet damage and very limited effective range, meaning it’s only truly dominant in enclosed spaces.
USG-90
USG-90 – Best REDSEC Loadout
- Optic: OSA-7 1.00x
- Muzzle: Double-Port Brake
- Barrel: 264MM Prototype
- Left Accessory: 5 MW Green
- Ergonomics: Mag Catch
Loadout Summary: This setup doubles down on CQB dominance. The Double-Port Brake and 264MM Prototype tighten your roar of bullets just enough to keep them on target at short range, while the 5 MW Green laser boosts hip-fire so you can dump rounds while sprinting and sliding. Mag Catch helps you reload that 50-round mag faster, keeping you in the fight instead of stuck in long reload animations.
USG-90 – Tips & Usage
- Treat the USG-90 as a room-clearing hose—it’s built for wiping squads inside buildings and tight cover.
- Abuse hip-fire whenever possible; ADS only when you have time to stabilize and track.
- Avoid long lanes and open fields; almost any rifle will beat you past short range.
- Use your huge mag to pre-fire corners and doorways without worrying about instantly running dry.
5. C-Tier SMGs
C-Tier SMGs are outclassed in the current meta, but they can still work if you build around their strengths. They usually demand stricter positioning, better aim, or more patience, and are best treated as stepping stones until you unlock higher-tier picks.
5.1 SL9
The SL9 is a versatile Engineer SMG with a unique design and solid all-round performance, but it lacks the raw killing power of top-tier options. Its recoil and range can be tailored for mid-range fights, making it serviceable if you prefer a more controlled playstyle.
SL9
SL9 – Best REDSEC Loadout
- Optic: OSA-7 1.00X
- Muzzle: Compensated Brake
- Barrel: 9″ Fluted
- Underbarrel: Factory Angled
- Magazine: 30RND Magazine
- Ammunition: Hollow Point
Loadout Summary: This build pushes the SL9 toward mid-range consistency. The Compensated Brake, 9″ Fluted barrel, and Factory Angled grip work together to reduce recoil and tighten groupings, while the 30RND Magazine gives you enough rounds to finish targets cleanly. Hollow Point adds extra headshot lethality to compensate for its otherwise modest killing power.
SL9 – Tips & Usage
- Use the SL9 as a support SMG—hold angles, cut off pushes, and take safer mid-range fights instead of hard entries.
- Lean on headshots to make the most of Hollow Point, especially when fighting armored enemies.
- Focus on controlled bursts at 15–30 meters, where your recoil-tuned build is most effective.
- Swap to higher-tier SMGs like UMG-40 or SGX once they’re unlocked if you want more raw damage.
5.2 KV9
The KV9 is a high-fire-rate SMG with serious shredding potential, but its small magazine and limited range hold it back in REDSEC. When fully upgraded it can still erase players up close, yet it demands careful ammo management and disciplined engagements.
KV9
KV9 – Best REDSEC Loadout
- Scope: 2PRO 1.25X
- Muzzle: Lightened Suppressor
- Barrel: 5.5″ Factory
- Underbarrel: Alloy Vertical
- Magazine: 23RND Magazine
- Ammunition: FMJ
Loadout Summary: This KV9 build aims to tame the gun just enough to make its fire rate usable. The Lightened Suppressor and 5.5″ Factory barrel keep handling quick while slightly smoothing recoil, and Alloy Vertical improves stability during short sprays. The 23RND Magazine gives you a bit more breathing room over the smallest mag sizes, while FMJ helps punch through armor and cover in close brawls.
KV9 – Tips & Usage
- Think of the KV9 as a close-range specialist that should almost never be fired past short distances.
- Play around cover and commit to very short bursts so you don’t waste your limited magazine.
- Always reload after each engagement; 23 rounds disappear extremely quickly at KV9’s fire rate.
- Use flanks and surprise angles where you can dump your mag before enemies have time to react.
