After the sneak-peaks of the last few days, here is the full country-specific assets showcase!
While designing each countries, I tried to follow so self-imposed rules to make sure that each of them would share a common gameplay style, but would also be unique enough :
-One veteran core unit per country;
-Two unique assets per countries;
-Four assets that replace core assets. Plus, each core assets cannot be replaced by more than one country specific asset (exemple : the Hammer Tank cannot be replaced by more than one country).
With that being said, let's start with the USSR arsenal.
Note : Every assets are subject to change.
==========USSR==========
The USSR relies on brute force. Its units are simple in design, having mainly more firepower and armor than the Soviet vanilla arsenal. For this reason, most of the unique units from the USSR cost more than their vanilla counterpart.
Veteran unit : Tesla Trooper
Volkov Soldier
Replaces the Soviet Komissar 
Role : Tactical super infantry
Weapon : Heavy AT Rifle + Airstrike Flare
Prerequisite : Barrack + Battle Lab
Note : Born from the destroyed Volkov Cybernetic Program. In essence, Boris from vanilla YR, without the build limit.

Battlemaster Tank
Replaces the Hammer Tank

Note : The Battlemaster has double the firepower of any MBT. However, it is more expensive than the vanilla Hammer Tank.

Twinblade
Replaces the Piranha

Scavenger
Replaces Mine Layer 
Role : Offensive credit generator, Deminer
Weapon : Rotative Steel Grinder
Prerequisite : War Factory + Service Depot
Note : In an attempt to counterbalance the higher cost of USSR's uniques units, vehicle and building destroyed by the Scavanger grant 10% of the destroyed unit's value. Also, it detects cloaked units at short range and is immune to mines.

==========Eastern Republic==========
The Eastern Republic uses weaponized radioactive armament. It has more tactical options, more mobility and can defend more easily than the vanilla Soviet, but most of its unique assets explodes violently when destroyed, damaging everything nearby.
Veteran unit : Piranha
Desolator
Replaces the Tesla Trooper 
Role : Anti-Infantry, Zone control
Weapon : Radiation Launcher
Prerequisite : Barrack + Battle Lab
Note : Is pretty much the same as in vanilla YR.
Sickle Walker
Replaces the Katyusha 
Role : Long range, Defense
Weapon : Grenade Launcher + x6 rocket
Prerequisite : War Factory + Radar
Note : More mobile than the Katyusha it replaces, it has a grenade launcher at short range to defend itself from infantry or light vehicle, and launches inaccurate rockets with a large AoE at long range. It can fires its weapon simultaneously. It can also deploy by digging into the soil to double its armor, but it can't undeploy after that, making it a permanent defense.

==========China==========
China's unique assets are lighter than what can be seen in the vanilla Soviet armament. However, they rely on infantry usage and countermesure, and uses buffs and debuffs to even the battlefield.
Veteran unit : Pyroscript
Tank Hunter
Replaces the Flak Trooper 
Role : Anti-Vehicle, Anti-Air
Weapon : Laser guided AT missile launcher
Prerequisite : Barrack
Note : The Tank Hunter's weapon works in two phases. First, it uses a laser to geolocalize the position of an enemy vehicle, and send this information to every other unit under the chinese general's command. In simpler terms, the vehicle is affected by a debuff which lower its armor by 25%. After this first phase, the Tank Hunter launches a missile at the target. In essence, the Tank Hunter is an debuff unit, affecting only vehicle.

Troop Crawler
Replaces the Flak Track 
Role : Recon, APC, Anti-Air
Weapon : Auto-Cannon + AA missile
Prerequisite : War Factory
Note : The Troop Crawler is more armored than the Flak Track, and comes with 5 Conscripts when build. Even if the weapons are different, its DPS is the same.

Helix
Replaces the Kirov Airship 
Role : Offensive/Defensive Balloon Hover Support
Prerequisite : War Factory + Battle Lab
Note : The Helix is not armed per se, but it is equiped with propaganda speaker and radar. Being mobile, it can follow armies by giving them an edge in battle by buffing friendly units (+25% firepower/armor) and debuffing enemy vehicle (-25% armor, just like the Tank Hunter). Therefore, the Helix can convert almost any group of unit in a much bigger threat than it really is.

That is all for now. The Allied country-specific assets will be shown soon.
Looking good! But I think the decal of the Propaganda Tower effect for infantry is too big.
You're kinda right, but it's a bit too complicated for the engine to have different animation like these on vehicle and infantry. Plus, you would not be able to see the sickle and hammer if it was smaller, I think.
