You are restricted to 3 uses of Elite Replacements per mission, but this is worth 3 points on the traits table.
Of course this works better with power 4 + trophy. Because this runs on prestige.
By doing this, you will actually END any use of elite replacements on the battle field.
But, you will get to keep all of the XP at the end of the mission.
This is really the only place you make a hard call. and decide if you want to do this.
In general, keeping all your XP at the end of the mission should over time averages out to more XP saved, after about 2~3 missions.
So we are playing averages and percentages.
Now... once your survive the mission, you are in the clear.
The way you work around Green Army is to "upgrade" your army.
For example, if I want to preserve 1377 XP on my pioniere, I will first "upgrade" it to a Wehr Inf. Make the choice and purchase. Back on the deployment screen, the unit is back to full health, and retains its 1377 XP, and I get refunded some prestige.
Then, since what I really want is my XP AND my Pioniere I am going to update that Wehr Inf back to a Pioniere.
And thus, you have refilled that Pioniere at the expense of prestige, but lost no XP.
This basically functions as elite replacements even though the actual Elite Replacement button is already grayed out from the unit command bar, so you can use it more than 3 times.
The more money you have of course, the more negligible this XP exchange will be.
other notables:
- By doing this, the first 3 times actually are still using your Elite Replacements allocation. But this just allow you to upgrade-refill your units beyond the 3 time limit.
- The 3 Elite Replacement you use are from the current mission. This means you will have no battlefield Elites to use.
- Since you only have one fighter type until the pick for Africa/Bararossa, prior to that you should use the Elite Replacements on fighters. Because there is no alternative to upgrade to. Do this first.
- You need a unit different than what you are currently fielding to upgrade to in order for this to work.
- You always get a refund when downshifting into an inferior unit, and pay a price when shifting back into the unit you actually use.
- You will need to double check the vehicle assignment on tow arty and AA, because the vehicle compatibility is different for a lot of them.
