Last War F2P Rush Guide: How to Unlock Tier 10 Troops

To unlock Tier 10 (T10) troops as a free-to-play player in Last War within roughly 157 days, you must rush your base directly toward Headquarters Level 30 while funneling all research currency into the Special Forces tech tree. Achieving this milestone without spending real money requires skipping non-essential base upgrades, hoarding Valor Badges exclusively for military research, and timing major building pushes with Alliance Duel events.

Core Prerequisites for Tier 10 Troops

Before you can research and train Soldier X units, your base must meet four hard milestones:

Headquarters Level 30: Unlocks the maximum level cap for your secondary infrastructure.
Tech Center Level 30: Uncaps the final tier of military research projects.
Barracks Level 30: At least one Barracks must reach Level 30 to unlock T10 unit training and promotion.
Special Forces Research Branch: You must complete the prerequisite path of nodes in the Special Forces tree that terminates in the T10 troop unlock.

Diverting construction queues, speedups, or resources into secondary unit centers, non-essential economy buildings, or decorative plots will significantly extend the 157-day timeline.

Headquarters 30 Building Progression

Rushing your Headquarters to Level 30 requires upgrading only the mandatory prerequisite structures for each consecutive tier. Do not pause to max out your entire base at each HQ level.

Milestone Phase	Primary Building Targets	Secondary Focus
Days 1–60	HQ 20–24, Tech Center, Alliance Center	Tank Center, Wall prerequisites
Days 61–110	HQ 25–28, Resource Depots	Level 20+ Barracks, Radar upgrades
Days 111–157	HQ 29–30, Tech Center 30, Barracks 30	Hospital capacity, final pre-tech requirements

To maintain continuous building queues on a zero-dollar budget:

Harvest high-level resource tiles on the world map constantly.
Clear all daily radar tasks.
Plunder inactive bases during Warzone Duel phases up to the daily resource limit.
Start major multi-day building projects exclusively during Alliance Duel Build Day to earn milestone chests containing universal speedups and resource packs.

Special Forces Tech and Valor Badge Economy

The Special Forces tech tree is the primary bottleneck for free-to-play accounts because the lower tiers require thousands of Valor Badges (Courage Medals) and heavy gold investments.

Valor Badge Allocation

Valor Badges gate end-game combat research. Misspending them on Garage upgrades or non-essential early trees will halt your T10 progress at HQ 30.

Save Badges for Special Forces: Reserve every Valor Badge strictly for the central branch of the Special Forces tech tree.
Max Alliance Duel Chests: Aim for all nine individual reward chests on daily Alliance Duel events, which serve as the primary free source of Valor Badges.
Spend Alliance Honor on Badges: Buy the full weekly allotment of Valor Badges from the Alliance Honor shop before purchasing other items.

Research Priority Order

Within the Special Forces branch, invest only in the prerequisite path required to reach Soldier X:

Unit HP
Unit Defense
Unit Attack
Morale

Avoid branching into optional side nodes until you complete the final T10 unlock node. Always activate research speed boosts—including alliance help, ministry titles, and active base buffs—before starting multi-day tech projects.

Resource Chest and Speedup Management

Universal speedups and resource chests must be handled with strict discipline:

Hold scaling resource chests: Level-scaling resource boxes determine their payout based on your current base tier. Keep these chests sealed until your Headquarters reaches Level 28 or higher. Opening them during the final push to HQ 30 and Tech Center 30 supplies the massive iron, food, and coin reserves required without leaving open resources vulnerable to enemy raids.
Align speedups with events: Never spend large batches of universal speedups outside of Arms Race or Alliance Duel scoring windows. Syncing upgrades with these events repays portions of your investment through diamond rewards, recruitment tickets, and speedup refunds.

Troop Training and Promotion Strategy

Training brand-new Tier 10 soldiers from scratch requires substantial time and resources.

The most resource-efficient method is to continuously train Tier 9 (T9) troops throughout your progression to HQ 30. Once the T10 research node finishes in the Tech Center, use your Level 30 Barracks to promote your existing T9 pool directly to T10. Promoting units requires far fewer training speedups and resources than raw training, allowing you to deploy full combat squads immediately upon completing the unlock.
