But I was. Twice.
Somewhere mid-mission at Raseiniai and then again at Smolensk. So what? Doesn't mean that I have to resort to regular repairs then. Just wait a few turns and save the RPs until you can elite repair again.
Regular repairs are solely done to 5-star units with about 1HP damage (or in case of emergency )
Basically I would consider it bad play or would have made some stupid mistake if the KV2 unit takes more than 1-2HP damage per mission. Only unit I don't care about are recon planes. They get shot down regularly.
And sometimes I go with regular repairs for engineers, too. Although cheap, they suffer huge losses every time, whether they're attacking, being attacked or shot at with arty...
Sorry, don't understand this part.
I get it, with them combat results being somewhat randomized, the huge infantry losses can vary from 2-6 HP sometimes.
But if you run some tests with the editor, one inf with AT support and one without, using the same attacking and defending units, both full HP and efficiency - you'll see. Same with planes.
