Tactics

Tank's sutability for commonly used tactics based on tank's top stats and compared to others in the battle. Personal experience is not considered

In:

Peek-A-Boo Not recommended Not recommended

You hide behind a cover, fully reload your gun, pre-aim and sneak out just for a second to make one damaging shot. Before enemy realizes you are hidden again. Decent mobility and aiming stabilization and you surely can pull this one off.

Long range sniping Not recommended Not recommended

Hiding in the bush on the hill and shooting at enemies on the other side of the map. If you don't mind all the hate that comes with it then you just need good dispersion and penetration to make every shot count.

Front Line Average Not recommended

Forget rocks, hills, buildings and all other cover. Make youself a cover for your teammates. Of course, this works only if you have very good armor and know how to use it or… well if you're already dead.

Circle Of Death Not recommended Not recommended

Drive behind slow tank destoyers and heavy tanks and keep circling around them to avoid being hit while making easy shots into the back of the enemy. Good traverse speed and acceleration is required.

Hit & Run Not recommended Not recommended

Hide in the bush, spot the enemy without being seen. Take a shot and start running. Fast. Repeat until no enemies left. Master this technique and there are many masteries coming your way.

1 vs 1 brawl Not recommended Not recommended

Who would win in 1 on 1 brawl depends on too many variables. Armor, guns, mobility, tanks sizes and many others. One thing for sure: without good DPM it's better to stay in the group or keep your distance.

Historical Reference

The IS-1 (IS-85) heavy tank was a thorough modernization of the KV-1. The tank featured the 85-mm D-5T gun. The IS-1 entered mass production in October 1943, but work was discontinued at the beginning of 1944, as the IS-2 (IS-122) tank entered mass production in December 1943. A total of 107 vehicles were manufactured.
