TrenchLine:Tower Defense Troop Tier List by Role
S through C rankings for economy, road DPS, armor break, AA, and naval troops in the current meta.
How this tier list is ranked
This TrenchLine:Tower Defense troop tier list ranks units by role value on current public lobbies after the Flood update line (through v0.25.0 thinking). Criteria: wave coverage impact, upgrade efficiency, map flexibility, and co-op contribution. A unit can be S-tier for AA and B-tier as generalist DPS—read the role columns, not only the letter.
Use this beside Best Loadouts and the full roster on Troops. Enemy matchups live on Enemies. Patch shifts are logged under Patch Notes.
Video mid-page covers troop and tier discussion for visual learners—pause and compare to your unlocks rather than copying blind.
Tier summary table
| Tier | Economy | Road / general DPS | Anti-armor | AA | Naval / support |
|---|---|---|---|---|---|
| S | Farms, FOB | PKM, Assault Squad (early) | SPG-9, PKM | Shilka | Rocket Barge, Fleet Command spend (HC) |
| A | Signaler | MG, Riflemen, Conscripts (AP max) | Battle Tank, tanks | MANPADS Team | Boats, Rocket Battery |
| B | Troop Spawner (skilled) | Marksman (post-nerf), mortars | Mortars into packs | Gunships | KPV, Troop Spawner support |
| C | — | Spec Ops (situational) | Underleveled rifles into armor | — | Cosmetic flex without water plan |
Letters assume correct placement. An S-tier Shilka on a blind tile plays like a C.
S-tier breakdown
Farms and FOB fund every serious clear. Selling them early for vibes is how Medium lobbies stall. Signaler sits just behind when teams actually stack its value—still excellent.
PKM earns S for armor and sustained lane work; community advice repeatedly points PKM at armored targets. Assault Squad earns early-game S after buffs—open waves cleaner than older Marksman habits.
SPG-9 is S for players who learn cone geometry. Misplaced cones drop it a tier; practiced cones delete Brute clumps.
Shilka is the AA benchmark. Flood and Hardcore lobbies without Shilka-quality air coverage leak to flyers.
Rocket Barge anchors naval DPS when channels matter. On Hardcore Tidefall, smart Fleet Command spends backed by Naval Tokens (Hardcore-only as of v0.25.0) also play at S when timed.
A-tier breakdown
MG and Riflemen remain A for reliable road uptime. Conscripts climb toward A/S when armor-piercing investment is maxed—plan the upgrade path.
Battle Tank and standard tanks are A for breakthrough work. Respect multi-tile footprints; poor Battle Tank seating is a common self-nerf.
MANPADS Team is A AA—bring with Shilka, not instead of all planning. Boats and Rocket Battery are A naval/artillery flex depending on map sightlines.
Signaler as noted is A+/S- depending on coordination.
B-tier breakdown
Marksman fell after nerfs. Still fine filler, no longer the unthinking carry. Mortars are B splash—great support, incomplete armor answer.
Gunships are B+ flex: helpful air/ground presence, risky as your only AA thought. KPV is B/A based on pier placement skill.
Troop Spawner is B rising to A in skilled hands after the v0.23.0 rework. Players who ignore the rework will swear it is C—the tool changed, not just the meme.
C-tier and situational
Spec Ops is Halloween-leaning spice. Fun in Easy flex slots; C for serious Flood/Hardcore planning if it displaces Farms or Shilka.
Any troop becomes C when massively underleveled into the wrong target: rifles into heavy armor, boats on dry Farmland ego placements, AA never upgraded past level one.
Role-first picking order
- Ensure economy (Farms/FOB).
- Ensure early clear (Assault Squad/Conscripts/Riflemen).
- Ensure armor answer (PKM/SPG-9/tank).
- Ensure AA if map/mode needs it (Shilka/MANPADS).
- Ensure naval if flooded (boats/barge).
- Then cosmetics and Spec Ops.
That order beats alphabetical collecting. More recipes sit in Best Loadouts.
Map modifiers to the list
| Context | Boost | Cut |
|---|---|---|
| Farmland Lake Easy | Road MG, Farms, Assault Squad | Heavy barge stacks |
| Flooded ports | Boats, Barge, Shilka | Pure Marksman bars |
| Hardcore Tidefall | AA, barge, token/Fleet Command | Economy-less glass cannons |
| Endless | Farms, FOB, Spawner skill | All-in wave 3 sells |
Community debate notes
- PKM vs armor — widely favored focus target advice.
- SPG-9 cones — high skill ceiling; placement separates S from B performances.
- Battle Tank four-tile debates — measure twice on your patch before blaming balance.
- Marksman nerf — stop building 2025 muscle memory.
- Assault Squad early buff — slot it in openers.
- Spec Ops — event flex, not a harbor plan.
How to use the YouTube breakdown
Watch with your loadout screen open. Note which units the creator treats as must-bring versus flex. Cross-check anything that contradicts v0.25.0 token rules or the Troop Spawner rework against Patch Notes. Creators filming pre-Flood will underrate boats—filter advice by date.

Frequently Asked Questions
Quick answers to the most common TrenchLine questions.
What is S-tier in TrenchLine right now?
Farms and FOB for economy, PKM and early Assault Squad for DPS, SPG-9 for cones, Shilka for AA, and Rocket Barge plus smart Hardcore Fleet Command spends for naval.
Why is Marksman lower than before?
Marksman was nerfed. It remains usable B-tier filler but should not displace Assault Squad openers or dedicated MG/PKM lines.
Is Battle Tank S-tier?
Usually strong A-tier breakthrough. Tile footprint mistakes make it play worse than its damage sheet—practice placement before Hardcore.
Do naval units matter on every map?
They spike on Flood maps and Hardcore Tidefall. On dry Easy farmland, road economy and DPS still lead.
