For the first time, sign a contract to earn a new non-Mercenary Premium tank when it’s first released. Learn all about the Chi-Se heavy tank here!

You might have signed contracts and earned tanks with them before. You might have bought Premium tanks before.

But never before have you been able to earn a non-Mercenary Premium tank with a contract right at the tank’s launch.

Start 2026 with a fresh approach. Sign the latest contract to claim the brand-new Japanese Tier VIII Chi-Se Heavy Tank!

When you take on any contract, you get the chance to earn a tank by completing a series of tasks over several stages. You’ll earn additional rewards as you complete each stage, too, including Consumables, Silver, Boosters, and even Premium Account time.

That remains true with the contract for the Chi-Se. This powerhouse is a heavy tank, but it doesn’t play like your typical Japanese heavy. Instead of positioning it on the frontline, deploy it as a support vehicle to make the most of its strengths.

• The Chi-Se’s armor will do well against enemies of the same tier, but avoid facing higher-tier enemies head-on.
• Use its 13 degrees of gun depression to play hull down and maximize the effectiveness of its sloped armor.
• Once in position, unleash this tank’s gun with its 330 alpha damage and 2,200 DPM potential to take down opponents methodically and systematically.

Remember, the Chi-Se is available at launch only via this contract. Don’t miss this opportunity to make it yours!

Here’s what else you should know about contracts in general:

• You can have only one contract active at a time! Once you’ve signed a contract, choosing a new contract will cause you to lose any progress made on the one you’re currently working toward.
• Certain tasks might have tier or class restrictions, but otherwise, each contract can be completed using either World War II or Cold War tanks. Choose your vehicles wisely!
• Each tank's contract can be completed only once (unless you previously completed that tank's contract prior to December 2020). Once you complete the contract's final stage, you won't be able to take on that tank's contract again.
• You can use Gold to skip certain stages! The buyout amounts for each stage will be listed with the other contract details below. Buyouts for the Chi-Se will be available through March 23.

Take a look at all the contract details below. Then head to the “Contracts” tab in game to start earning this tank!
