Two additional tank types for Tank Chess: Ultra-heavy Tank and Armed Off-road vehicle. The Ultra-heavy Tank (UT) is the strongest and the slowest vehicle. Its max speed is only 1 and its armor values are V, IV and III. On the front, it has a turrent with a double-barreled gun that shoots in three directions and has a value of V and in the back there is a smaller turret with another cannon (III) that shoots in three directions backwards. Like the Twin-gun Tank, the UT can also shoot at two targets simultaneously. On top of that, being a heavy means that it can destroy tree-type obstacles. The Armed Off-road vehicle (AO) is the fastest piece in the game (max. 7 speed). The AO movement is different from the other pieces: it does not lose movement steps due to turning. Because of this, it can move even further, but at the same time it cannot rotate in place. Therefore, in each step this piece can move to a square that is right in front or to the squares that are left or right to that square. When moving backwards, just like any other piece, Armed Off-road vehicle can only move once to the square that is right behind. But in this situation it may also turn at 45 degrees simultaneously (left or right). The AO does not have any armour (0, 0, 0), and it has a recoilless gun that can shoot only right in front due to the mounting. The gun is weak(it has a value of I) and its range is limited to 5 squares (even though it can shoot over obstacles), which is another distinctive feature. —description from the rules
