Does anyone know how this actually works?

Obviously XP gain is dependent on various factors: Attacker type, defender type, Kills, (Supressions for Art & SB). However what other factors are there?

Current XP is one obvious one - ie XP gained goes down as current XP rises.
Defenders current XP? ie a 0 xp unit attacking a 0 XP unit gains less per kill than if it attacks a 200xp unit?
Defenders Entrenchment?
Defenders long term supression? Ie attack with arty to suppress him but then your combat unit gets less XP? This definitely happens, I just can't figure out how this is worked out.
Does the actual unit model make a difference for attacker or defender? ie an 88 attacking a T34/41 gains more XP than a Marder attacking the same target? Or an 88 attacking a KV2 gains more XP than if the same 88 attacked the T34/41?

If these all do factor in then the XP gain formula must be one horrendously complex beast.

Anyone know any more?

Dunno about all factors, but...

Defenders current XP? ie a 0 xp unit attacking a 0 XP unit gains less per kill than if it attacks a 200xp unit?
Defenders Entrenchment?

I *think* I saw a post somewhere here that attacking high XP units gives back higher XP indeed than fighting green units. I could be wrong though.

I'm wondering myself whether unit type or price plays any role, for example if cheaper units gain more XP when fighting expensive ones.

It's like the recipe for Coca-Cola, top secret but oh so good!
