I need to quote the manual:
That suggests that a soldier can gain 2 points in each attibute per battle.
But I have not been able to make any soldeir gain more than +1 to STR, ACC or RFL (TUs are very easy to gain).
Has anyone been able to train any skill other than TU and BRV at +2 per mission?
And if so, what are the thresholds?
For instance, you only need 1 shot to gain +1 ACC and +1 RFL.
