"During battle, the T-70's drawbacks become apparent. Commanders have alerted GABTU of this. Commander of the 1st Tank Brigade, Colonel Chukhin, points out the following:
- The T-70 commander has difficulty when simultaneously observing the battlefield, loading the gun and machinegun, and firing on targets. The company commander's job is even harder, as aside from all this he must command the company. The turret must be widened to fit 2 men.
- The armour of the T-70 is weak, and can be penetrated with a high caliber machinegun. T-70 tanks have to be used in the third echelon to fight enemy infantry, where the powerful armament, the 45 mm gun, is not used to its full potential.
- Reinforcing the suspension.
- Increasing engine power.
- Increasing turret for two men.
