Battlefield 6 Field Specs Guide (2025): All Classes, Perks, and Tier Progression Explained

Battlefield 6 introduces a new layer of tactical depth through its Field Specs system — a dynamic set of class-bound specializations that evolve during a match. These powerful upgrades reward players for playing their role effectively, unlocking both passive perks and active abilities as you gain score.

Whether you’re charging into objectives as an Assault, repairing vehicles as an Engineer, or spotting enemies from afar as a Recon, mastering Field Specs can turn the tide of battle. This guide covers everything you need to know — from how the system works to every class specialization and tier progression example.

This article is part of the “Battlefield 6 Guide” collection, offering a complete troubleshooting process that combines automated solutions and manual fixes to resolve common issues.

What Are Field Specs in Battlefield 6?

Field Specs are match-specific specializations tied to each class. They stack on top of your core class passives and weapons, enhancing your combat efficiency and role identity.

Each specialization caters to a different playstyle — from breaching fortified objectives to providing medical support or disabling enemy vehicles. The deeper you lean into your role, the stronger your Field Spec becomes.

How Field Specs Progress During a Match

Each Field Spec levels up through a four-tier system as you earn score in a round. Progression is tied to core gameplay actions — capturing objectives, getting kills, reviving allies, repairing vehicles, or resupplying teammates.

As you climb the tiers:

• New passive bonuses unlock automatically.
• The final tier grants an active ability, usable for a short duration to deliver a tactical power spike.

Key details:

• Field Spec progress resets at the end of each match.
• You can switch classes mid-round, and progress for each class is saved separately.
• Skilled players can fully upgrade multiple Field Specs in one match through active teamwork and contribution.

Choosing the Right Field Spec

Success in Battlefield 6 often depends on adapting your specialization to the situation. Here’s how to decide:

• Assault:
  • Breacher excels at breaching objectives with explosives.
  • Frontliner suits aggressive players who want rapid healing and spawn boosts for their squad.
• Engineer:
  • Anti-Armor dominates vehicle-heavy maps.
  • Combat Engineer is vital for teams relying on vehicle support and repair strength.
• Support:
  • Combat Medic is perfect for revive-heavy gameplay or defensive standoffs.
  • Fire Support shines during sustained firefights requiring steady ammo and turret support.
• Recon:
  • Sniper provides unmatched control over sightlines and enemy intel.
  • Spec Ops benefits stealth-oriented players who prefer flanking and covert spotting.

💡 Pro Tip: Don’t hesitate to swap classes mid-match. If your team’s push stalls, switch to the spec that solves the problem — clear armor, strengthen defenses, or expand intel. You’ll retain any progress earned on your previous specs.
