Which unique units or unique infrastructures would you like to see?

[Havendish]

PERSIA
Aswaran (Sawaran) for Persia instead of calling them Cataphract (that's for Byzantium). Heavy Cavalry less powerful than Cataphract on impact(attack) although still very potent, but also carrying bows for ranged attack (before engaging in melee)

ASSYRIA
famous for their Chariots, so perhaps a boost or UU there

POLAND
Ulan Cavalry. Brought in by their second great leader leader: Jozef Pilsudski who is largely responsible for Poland's rebirth after WWI. Excellent modern cavalry, carried rifles, lances and sabers (and even field cannons)

RUSSIA
T34 tank - superior to generic tanks
MIG fighter/bomber (several models to choose from)
KATYUSHA moblie rocket launcher
STRELTSY - musketmen replacement, slightly more damage than musketman when firing-modified musket, also armed with Berdiches-heavy axes on long shafts which held the musket in line when firing and also a very useful weapon when it switched to melee fighting (would combine gunpowder and melee ability)

But they adopted the Heavy Chariot from the Mitanni, so perhaps what they were really famous for: Siege Engines/Siege Towers when everyone else is still messing about with simple Battering Rams?

Or, the 'Tachanka' or Machinegun Cart, a Unique Modern Mounted Ranged unit - a Horse Archer for the Twentieth Century. It was invented by a Russian Nationalist during the Russian Civil War, but the Polish Army adopted them wholesale and they allowed immediate ranged fire support to keep up wth the fastest cavalry.

RUSSIA
T34 tank - superior to generic tanks
MIG fighter/bomber (several models to choose from)
KATYUSHA moblie rocket launcher
STRELTSY - musketmen replacement, slightly more damage than musketman when firing-modified musket, also armed with Berdiches-heavy axes on long shafts which held the musket in line when firing and also a very useful weapon when it switched to melee fighting (would combine gunpowder and melee ability)

T-34 was not really superior to other tanks in combat, except for a narrow 'window' in late 1941 - early 1942, but it was much cheaper to produce and maintain: perhaps a Production Cost drop from 80 to 65 and a Maintenance Cost drop from 4 to 3?

The famous WWII 'Guards Mortars' (Katyushas) all had much shorter ranges than regular artillery (4 - 10 km versus 12 - 18 km), so perhaps a Substitute Ranged Unit, instead of the Machinegun, with a much higher Ranged Effect and higher mobility, and the ability to Move After Combat (they were truck-mounted and the tactics were to 'fire and run' since they were so short-ranged)

Streltsy would make a good Russian version of the new Pike and Shot unit in R & F: slightly lower Anti-Cavalry factor, but higher Melee and Ranged Factor. They were also used a lot as 'Town Militia' right down to the time of Peter the Great, so perhaps a 0 Maintenance Cost if used to Garrison a City for them.

But they adopted the Heavy Chariot from the Mitanni, so perhaps what they were really famous for: Siege Engines/Siege Towers when everyone else is still messing about with simple Battering Rams?

Siege Engine: Replaces the Battering Ram. Stacked Melee units do full damage to city walls. Stacked Ranged units have +1 Range and ignore Walls.
