I knew them at this side. The terms are just used smoothly so don’t worry about Urdu word or English word.
In my version:
Sepoys would be adjusted to be delayed to the Fortress Age, to represent that they were used later when British came.
Banduqchis would be the cheap skirmishers replacing the current Gurkhas, similar to Strelets and available in the Commerce Age.
Shamsherbaz would be just the units renamed from the current Rajputs.
Honestly I don’t like the regular units get a clear relation to the ethnic groups on the name directly. So I rename Marathan Catamaran “Bandit Catamaran” too.
On the other hand, Gurkha Riflemen, Rajput Cavalries and Marathan Light infantries would be new mercenary units for the Indians and other civs, to present the distinctiveness and the identity of the history of their groups.
The stable buildings would be renamed “Stable” clearly.
Sowars would use the new module, riding horses rather than camels.
Mughal Archers would be the new cavalry archer units, available in the Commerce Age, weaker than regular Cavalry Archers but able to fire multiple arrows at once.
Camel Riders would be the new heavy cavalry units, available in the Fortress Age, using the module of the original Sowars, having attack bonus against cavalry.
Zamburak would be adjusted to be available in the Fortress Age.
Dhows and Gurabs would be the new units to replace the European style Caravels and Galleons.
Since the wonder mechanic would be replaced, the abilities of wonders like Inspiration, Cease Fire and Imperial Service need new place to depend. I think it is reasonable to give a lord hero these abilities, similar to the Chiefs. Due to the abilities, the lord would be expected to become the center of the Indian army as the game goes by. So I actually hoped you Indian friend can like and support this idea. It is a shame that the Zamindar or Mansabdar cannot be used to a hero here.
If the sowar becomes the explorer, we have to find an another name to rename the cavalry. Also, it may not mount an elephant.
Edited: Imperial Court is already used at the Home City. I google the term “Diwan-e-aam”, seems it also can be called “Hall of Audience”. Is it accurate?
