It's not unit upgrades, but purchased upgrades like going from cavalry to gunships.

And it's the Kremlin fyi.

While we're talking about unit upgrades and promotions, could someone please tell me how many XP are needed for each promotion? I've done an extensive search and didn't find the answer anywhere.

... If I upgrade, do I lose those promotions? Or do they become something else (just go to Combat II, Combat III, etc)? ...

IIRC, you keep all promotions the unit had before upgrading even if the unit to which you are upgrading does not have this promotion when built from scratch. I'm not sure about the patch 1.08 version.

It is in the manual and should be somewhere in xml? The manual says 2 xp for a first one, 5 more for the second, 10 for the third and 17 for the fourth. Don't know about fifth.

I believe it has an increasing increase
so its 26, 37, 50...
2+3=
5+5=
10+7=
17+9=
26+11=
37+13=
50+15=
65....

(although I'm not sure how high up it actually goes)

 

[Amao]

The promotion levels look like n^2+1.
such as 2 = 1*1 + 1, 5 = 2*2 + 1....

Thanks a lot guys. And great observation Amao; it's much easier to remember like this. Everytime you sit on a square, it's around the corner. Easy!

Correct me if I'm wrong, but I think Kremlin allows you to hurry a building (not sure about units) at half cost, not upgrade units.

As for promotions, I promoted a medic cavalry to gunship and it kept the medic icon, didn't check to see if it actually worked though.

From what I have seen you keep and can use promotions when you upgrade even if they are not available to your current unit type.

e.g I had a swordsman with the "city raider I & II" promotion and upgraded him to a grenadier. when I went to attack another grenadier in a city and it showed he still had +45% bonus even though this promotion is not available to gunpowder units.

Hmm, just thinking this can be a very useful exploit. If you don't have any civics or wonders that boost your experience (i.e. Theocracy/West Point) and you just want to make the best use of the one promotion your barracks will give you to attack a city (and you have a little money to spare) build a maceman, give him city raider and upgrade him to a grenadier! This will give you an extra 10% above what you would have got with Combat I.

Another example:
You've got to go and fight a Rifleman defending a city. You can build a unit that will get 3 promotions. The best attacking unit available to you is also Rifleman

Option 1: Build Rifleman and take Combat I, II and Pinch = bonuses of +45%*
Option 2: Build Maceman and take City Raider I, II and III = bonuses of +85%!! (note the extra +10% vs gunpowder for City Raider III). Then upgrade to a Rifleman

Going for Option 2 gives you a relative strength of 25.9 vs 21.75. It all depends on whether or not you want to spend 145 gold for the extra strenght (note though you are also saving 40 production)

I presume you can also use this to give gunpowder units first strike abilities if they were upgraded from archers.

(* from what I gather from the "combat explained" thread bonuses don't apply quite like this but I will explain it this way for simplicity purposes)
