Dragon's Soul IX

One of the strongest tier IX premium medium tanks.
It's not only good but it is also a fun tank to play with.
Use rocket boosters to get into position early, then play hulldown because your hull armor is kinda weak (except playing against the lower tiers).
Remember to keep couple of booster for escaping later on or ramming enemy tanks.
Alpha damage is good for tier IX mediums.
Be aware it's not created for sniping.

Same tank without 3d style: DZT-159
