There will be three types of battles included in the Random Battle Queue as of the 7.4 update: "Standard Battle", "Encounter Battle", and "Assault"
Two teams, with 15 vehicles per team, take part in one match. Each team has its own base (flag area) to defend. A team can achieve victory by either destroying all enemy vehicles or by capturing the enemy base. The battle can take up to 15 minutes, but if no one has achieved victory then the match is a draw.
This game mode can be played on all maps.
