76mm Artillery and Tank Gun Projectiles
76mm Complete Round, Fixed, Incendiary, UZ-344
This incendiary round is fired from the 76mm regimental gun (howitzer) M1943. The M1943 is obsolete in the Soviet Army but is standard in the Polish, Bulgarian, Czechoslovak, and Albanian Armies, and may also be found in Rumania and Yugoslavia.
The illustrated round is not interchangeable with standard ammunition used in other 76mm weapons. It is used to ignite such targets as timber structuresm, forested areas, and fueld and ammunition dumps.
Its projectile contains nine blocks of an incendiary thermite composition, and a black powder bursting charge. The T-6 fuze, with an adapter, is used with the Z-350 projectile in this round.
Note. The dimensions and markings on the cartridge case in the above illustration have not been verified.

Weight of propellant, w/o igniter: ?kg (? lbs)
Type of projectile filler: Incendiary composition and black powder
Weight of projectile explosive filler: 0.015kg (0.033 lb)
Packaging
The illustrated 5-round wooden box weighs approximately 58kg (128 lbs) when packed. This ammunition also may be packed in a 6-round box weighing 70kg (154 lbs), or in an 8-round box weighing 94kg (207 lbs).
76mm Complete Round, Fixed, Incendiary, UZ-352
This Soviet incendiary round is fired from the 76mm mountain gun (howitzer) M1909. It is used to ignite such targets as wooden structures, forested areas, and fuel and ammunition dumps. Its long-range steel projectile contains nine blocks of an incendiary thermite composition which generates a heat of 2,500 to 3,000 degrees centigrade.
When the fuze functions, its flash first ignites quick-matches in the incendiary blocks, and then ignites the bursting charge which expels the incendiary composition.

76mm Complete Round, Fixed, Smoke, UD-352
This smoke round is fired from the 76mm mountain gun (howitzer) M1909. Smoke rounds are used by the Soviets for denying observation to enemy firing points and observation posts, for laying wide smoke screens over entire sectors, for target spotting, and for other purposes. The common smoke compositions used in Soviet smoke rounds are phosphorus, sulfur trioxide, and chloride of tin.
Although the pricipal use of phosphorus is to produce smoke, it is an incendiary and casualty agent as well. It ignites spontaneously upon contact with air and continues to burn even when embedded in the flesh. The D-350 long-range steel projectile shown in the above drawing contains a yellow phosphorus smoke composition and a TNT bursting charge.
The UD-352 complete round may be found with either the D-350 or the D-352 projectile. The KTM-2 fuze is used with these projectiles in this round. As a component of other complete rounds, however, the D-350 is also used with a KT-2 fuze.
