List of Soviet upgrades

Upgrades purchased from war laboratories strengthen certain units in exchange for payment. The player is not limited in the number of upgrades and can have all of them at the same time. However, the impact of upgrades is still lower than that of secret protocols.
The article describes all the upgrades available for purchase when playing for the Soviet Union.
== Tier 1 upgrades ==
=== Infantry Armor ===
Equips all Conscripts, Flak Troopers and Combat Engineers with cheap body armor. Increases the survivability of the affected units by 10%.
=== An example to follow lvl.1 ===
Grants a 1% chance for each Conscript to turn into Spetsnaz when reaching heroic level.
Note: a Conscript who becomes a Spetsnaz does not retain the Infantry Armor upgrade effect, in case it is already purchased. Current HP also remains the same.
=== Propaganda towers ===
Equips all Barracks, Apocalypse tanks and Commissars with propaganda devices, the effect of which heals all allied infantry nearby.
== Tier 2 upgrades ==
=== An example to follow lvl.2 ===
If there is Commissar nearby, the chance of each Conscript turning into Spetsnaz is doubled (up to 2%)
Note: An example to follow lvl.1 must be already purchased
=== Element 111 shells ===
Shells hardened with Element 111 give Hammer tanks and Apocalypse tanks attacks 5% additional damage.
Note: upgrade also affects the additional weapon of the Hammer tank, but only if it does not have energy damage type (must not deal Tesla, Prism, Wave-Force, Asgard laser, or any magic damage)
