How to Unlock the Mammoth LMG in BO7 and Warzone Season 5
The Mammoth LMG is not available in the Battle Pass or Store in BO7 Season 5 or Warzone Season 5. Instead, the weapon can be earned exclusively by completing tiers in the Machine of War event, which runs from July 30 to August 13, 2026.
Players therefore need to progress through the event’s reward track before it ends to unlock the Mammoth. The Mammoth is a full-auto LMG equipped with twin reciprocating barrels, giving it serious damage while maintaining manageable recoil.
However, its heavier design results in slower handling, making it better suited to sustained fire than to fast-paced engagements.
To unlock it, simply progress through the Machine of War event tiers during its active period and claim the Mammoth when you reach its reward tier.
What Is the Machine of War Event?
The Machine of War is a limited-time event in BO7 Season 5 and Warzone Season 5 that lets players earn Fuel Cans and exchange them for rewards through a sequential progression track.
Fuel Cans can be earned by getting eliminations in Multiplayer, Zombies, and Endgame, collecting them from Warzone loot caches, and completing Ranked Play matches.
The reward track is divided into exchanges costing 10, 15, or 25 Fuel Cans, with players moving through the tiers in order until they reach the Black Ops 7 Mammoth LMG, which serves as the event’s final prize.
Want to see every weapon and its unlock method? Read our guide to the full Black Ops 7 weapons list. The exact number of Fuel Cans needed to reach the Mammoth is not certain.
The full reward track requires exactly 200 Fuel Cans across three reward tiers, which has been verified by players progressing through the event. However, the 10, 15, and 25-can tiered exchange system is the confirmed mechanic.
Fastest Way to Farm Fuel Cans
The fastest way to farm Fuel Cans is playing Warzone Casual Resurgence or Casual Battle Royale. Because these lobbies are heavily populated by bots, eliminations, which serve as a primary source for Fuel Can drops, are significantly easier to secure than in standard playlists.
For maximum efficiency, prioritise opening Supply Crates and hunting bots rather than engaging real players. Warzone Resurgence Casual is particularly effective because the high respawn rate allows you to cycle through loot areas repeatedly.
For a complete breakdown of the latest changes, check our Black Ops 7 Season 5 update and patch notes. Players report earning up to 30 Fuel Cans in a single Casual Resurgence match, meaning you can clear a full 25-can Tier 3 reward in just one session.
Warzone Lockdown Casuals is another option if you want additional loot opportunities. Supply Drones can be shot down to provide extra Supply Crates, although the mode tends to involve more combat and resistance.
If you don’t want to grind, there is also a paid shortcut. The Tracer Pack: Sentry’s Watch store bundle gives a Black Ops 7 Mammoth LMG blueprint immediately.
However, getting the blueprint does not fully bypass progression, as you’ll still need to level the weapon to unlock its full range of attachments.
Machine of War Reward Tiers
The Machine of War event allows players to redeem collected Fuel Cans across three progressive reward tiers, topped off with exclusive mastery items. Redeeming Fuel Cans grants items sequentially or randomly from each tier pool until the tier is completely cleared.

|---|---|---|---|
| Tier 1 | 10 Fuel Cans | Double XP Token Double Weapon XP Token Ironic Weight Weapon Sticker Mechanic Preparation Loading Screen Iron Bites Spray | Entry-level consumable boosts and basic cosmetic flair |

Mastery Completion And Event Summary
| Event Milestone | Total Cost Requirement | Unlocked Reward |
|---|---|---|
| Clear Tier 3 | Tier 3 Pool Complete | Mammoth Light Machine Gun (Black Ops 7 Weapon) |
| Mastery Completion | 350 Total Fuel Cans (Clear All Tiers) | Soul Eater Animated Universal Camo |
Clearing Tier 3 awards the Black Ops 7 Mammoth LMG, while fully redeeming all items across every tier (350 Fuel Cans total) automatically unlocks the Soul Eater Animated Universal Camo. Looking for easier matches? Check out our Black Ops 7 bot lobbies service and practice.
What Happens If You Miss the August 13 Deadline?
Missing the August 13, 2026, 10 AM PT deadline does not mean losing the Mammoth LMG forever. Once the Machine of War event ends, the weapon moves to the Armoury, where you can still unlock it by earning XP.
The same does not apply to the event’s cosmetic rewards, which are only available during the event and will be gone once it closes. Want to skip the grind? Buy Black Ops 7 accounts equipped with fully unlocked mastery camos, max-level weapons, and exclusive items.
Activision has not revealed the exact amount of XP required to unlock the Black Ops 7 Mammoth LMG through the Armoury, so there is no confirmed XP figure to provide yet.
For now, August 13 at 10 AM PT is the important cutoff if you want to earn the Mammoth through the event itself or collect its limited-time cosmetic rewards.
