I'm selling my old war thunder account as i don't play the game anymore. Here is an imgur album of the tech trees https://imgur.com/a/vNZ2S . The US plane one cuts off halfway but don't worry, i have the F-80 researched and the F-86 and F9F basically researched. The US, Germany, and Britain all have jets. There are a few rare planes in here as well. You can contact me on here.
