The "Off-road Patrol" update for Enlisted is getting a second round of testing. After players commented on the first test, Gaijin fixed a large number of bugs. They also made balance changes and adjusted the new off-road squads.
The test server opens on September 18 at 17:00 UTC and shuts down on September 21 at 09:00 UTC. Any Enlisted player on PC can join. You need a separate test client, which is installed apart from your regular game. Your account gets copied over, but nothing you earn or do on the test server carries back to the live game.
The goal is to catch bugs before the update goes live and to hear player ideas for improving it. The announcement links to preliminary patch notes, the test client download and a bug report form. General feedback goes in the matching forum thread.
