- T-34 tank: one 76 mm gun with a coaxial DT machinegun in the turret, a second DT machinegun for the radio operator, and one PPD in the turret for firing from hatches.
- KV tank: one 76 mm gun with a coaxial DT machinegun in the turret, a second DT machinegun for the radio operator, the third DT machinegun in the turret bustle, and one PPD in the turret for firing from hatches.
- Ammunition capacity of the T-34 and KV tank is established in the following amounts:
- For the KV tank: at least 115 76 mm rounds, 4000 machinegun rounds, and 500 PPD rounds

- The ammunition racks on the SP, T-34, and KV tanks must be comfortable to use and allow a rate of fire of 6-8 RPM on the move.
- The driver and radio operator observation devices on the SP, T-34, and KV tanks must show both fenders of the tank, block bullets and splash, and be quickly replaceable if damaged.To improve visibility while driving, equip the SP, T-34, and KV with an additional observation device. Install observation devices along the sides, one per side, for use by the driver and radio operator.

- The NKSM and NKTP must produce prototypes and prepare for production of T-34 and KV tanks with the aforementioned changes by January 1st, 1941.
- To allow for easy controls and increase the top speed of the SP and KV tanks to 40-50 kph and the T-34 tank to 60-70 kph, require the NKSM and NKTM to prepare prototypes and production for a planetary transmission for SP, T-34, and KV tanks by April 1st, 1941. Components of the planetary transmission must function until major repairs are required.

By August 1st, 1941, be completely prepared for full production to meet the needs of the tank factories and the NKO.
- The NKO and NKSM, must examine the sensibility of the front hatch in the T-34 model 1940 tank and determine the possibility of installing triplex observation blocks instead of the mirror panels within 15 days.
