The Rainbow Six Siege weapon tier list for defenders has not received any significant changes with the Y10S1 update. This means that most of the top-rated guns in Siege's arsenal have maintained their spot in the meta. Having a dependable loadout is crucial when it comes to defending the objective site. Although defenders have the advantage in most maps in terms of cover and gunfights, high damage output weapons can help you during chaos as attackers rush to plant the defuser.
Rainbow Six Siege is a team game where ability synergy is important to win rounds. An effective entry denial setup can delay the attackers long enough for the defenders to launch flanks and engage in fights. However, winning these gunfights requires heavy firepower and consistent weapon choices.
This article will highlight the weapon tier list for defenders in Rainbow Six Siege.

Defender Weapons tier list for Rainbow Six Siege Deadly Omen (Y10S1)
Defending in Rainbow Six Siege provides you with ample time and opportunity to strategize reinforced walls, place shields (if available), and make rotations on soft walls where necessary. A reliable loadout can help you perform quick peeks, rotate faster, and pressurize enemies on certain entry points.
The Defender weapons mentioned below consist of all the primary SMGs, LMGs, DMRs, ARs, Shotguns, Secondary SMGs, and Machine Pistols. They're categorized into five tiers: S, A, B, C, and D. The S tier comprises the best weapons on the defensive side, whereas D has the most disappointing ones.
S tier

The top choices in this weapons tier list include arguably the best guns on Defense in Rainbow Six Siege Operation Deadly Omen. They pack the most powerful punch across four different classes of weapons. These are the cream of the crop when it comes to LMGs, SMGs, DMRs, and Shotguns, excelling in fields like fire rate, damage per second, TTK, and effective range.
- ALDA 5.56 (LMG 1x for Maestro)
- MP5K (SMG 1x for Mute, 2.5x for Wamai)
- T-5 (SMG 1x for Lesion, Oryx)
- AR-15.50 (DMR 2.5x for Tubarao)
- MK 14 EBR (DMR 2.5x for Aruni)
- M590A1 (Shotgun 1x for Smoke, Mute, Warden)
The ALDA 5.56 is one of the best LMGs in the game that defenders can use to provide suppressive fire. Maestro can use this to pummel bullets through soft walls and rotations to deter attacker rushes while keeping his Evil Eye active to poke opponents.
The MP5K is a great choice for hit-and-run strategies. It is also great for sustained mid-range fights due to its magazine size and comparatively quick reload speed. It has a small amount of gun kick, which makes it usable even in hip fire if necessary during close-quarter combat.
The T-5 has great recoil control, fire rate, and high damage output per magazine. This makes it great for roamers like Lesion who can place traps and play off sound cues and positional information.
The AR-15.50 packs a heavy punch but is a single-fire weapon. However, this ensures high accuracy and tactical play. You can score kills with a maximum of 3 body shots with this gun in medium and long-range situations.
The MK 14 EBR has less damage output per bullet than the AR-15.50, but compensates with a larger magazine capacity. It is another marksman weapon that depends on user's game sense and raw mechanical skills. It is a great weapon for holding long hallways or a cross angle toward different rooms.
The M590A1 is a shotgun that is perfect for holding close angles on entry routes. However, its lack of range can only be compensated for with a reliable secondary weapon like an SMG (if your operator loadout has the option). When picking this gun, you are likely going to commit to the objective site and play behind solid cover with some backup. The stopping power of this weapon in face-to-face gunfights (close-range) is unmatched and can be used to mow down entire attacker squads.
A tier

The A tier consists of some of the finest guns in the Rainbow Six Siege Defender weapons tier list. Although they slightly fall short in some aspects to qualify for the S tier, they are formidable for dealing with attackers.
Be it high fire rate, high damage per bullet, lethal range, or low TTK, these are amazing choices for any player to pick up and destroy attackers. The A tier in this Defender weapons tier list consists of four classes of weapons and numerous offer the added advantage of 2.5x ACOG sight. The classes are SMGs, ARs, Shotguns, and Machine Pistols. The weapons in this tier are,
- MP5 (SMG 2.5x for Doc, Rook, Melusi)
- MP7 (SMG 1x for Bandit, Fenrir)
- M870 (Shotgun 1x for Jager, Bandit, Thorn)
- 416-C Carbine (AR 1x for Jager)
- K1A (SMG 1x for Vigil)
- Vector .45 ACP (SMG 2.5x for Goyo, 1x for Mira)
- MPX (SMG 1x for Valkyrie, Warden)
- FO-12 (Shotgun 1x for Ela)
- TCSG12 (Shotgun 2.5x for Goyo, Kaid)
- SMG-11 (Machine Pistol 1x for Smoke, Mute, Solis)
- 9X19VSN (SMG 1x for Kapkan, Azami, 2.5x for Lord Tachanka)
- 9MM C1 (SMG 2.5x for Frost)
- Spear .308 (AR 1x for Thunderbird)
- MX4 Storm (SMG 1x for Alibi)
- FMG-9 (SMG 1x for Smoke)
- Supernova (Shotgun 1x for Echo)
B tier

This layer of the weapons tier list consists of a wide selection that falls significantly short in a primary aspect in Rainbow Six Siege, like fire rate, damage per bullet, range, or TTK. All the weapons mentioned below are known to struggle due to a sporadic recoil pattern that makes them inconsistent or low damage and bullet count, making them ineffective even at medium distances.
This tier in the defender weapons tier list includes weapons of four classes: SMGs, ARs, Machine Pistols, and Shotguns. Only a couple of the weapons come with the 2.5x; even then, areas like fire rate and TTK hinder their consideration for a promotion. The weapons in the B tier are as follows:
- Aug A2 (AR 1x for Wamai)
- Scorpion EVO 3 A1 (SMG 1x for Ela)
- Bearing-9 (Machine Pistol 1x for Echo, Thunderbird, Lord Tachanka)
- SMG-12 (Machine Pistol 1x for Vigil, Warden)
- P-10 Roni (SMG 1x for Mozzie)
- Commando 9 (AR 1x for Mozzie)
- UZK50GI (SMG 1x for Thorn)
- P90 (SMG 1x for Solis, 2.5x for Doc, Rook)
- MP5SD (SMG 1x for Echo)
- UMP45 (SMG 1x for Pulse, 2.5x for Castle)
- Aug A3 (SMG 1x for Kaid)
- ACS12 (Shotgun 2.5x for Azami, Alibi, Maestro)
- SASG-12 (Shotgun 1x for Kapkan, Fenrir)
- M1014 (Shotgun 1x for Castle, Pulse)
- SIX12 SD (Shotgun 1x for Lesion)
C-tier

The C-tier weapons consist of guns that are inconsistent and suffer from major flaws in more than one field required in a Rainbow Six Siege Defender weapons tier list. These choices might even put you at a disadvantage when in a match.
This tier in the defender weapons tier list consists of three classes of guns: LMGs, Shotguns, and Machine Pistols. Although one of the eight weapons in this tier features a 2.5x ACOG sight, it is quite unreliable and almost guaranteed to put an unfavorable end to your round with most scenarios. The weapons in the C tier are,
- DP27 (LMG 1x Lord Tachanka)
- C75 Auto (Machine pistol 1x for Vigil)
- BOSG. 12.2 (Shotgun 2.5x for Vigil)
- Super 90 (Shotgun 1x for Frost, Melusi)
- SPAS-15 (Shotgun 1x for Caveira, Thunderbird)
- SG-CQB (Shotgun 1x for Doc, Rook)
- ITA12L (Shotgun 1x for Mira, Solis)

D-Tier

This lonely class of weapons only consists of two guns, and these are the worst ones to get in defense for this meta. Every alternative for these weapons the respective operators have will perform better in every scenario. From damage per second to TTK, effective range, and fire rate, it doesn't get worse than these. The weapons in this category are,
- M12 (SMG 1x for Caveira)
- SPAS-12 (Shotgun 1x for Valkyrie, Oryx)
