Hello,
Are there any tips for gaining veterancy on units? For example, anything I should be mindful about, good rule of thumbs, etc.
I know sending units to their near death to only retreat is not a good idea, since that just gives your opponent a ton of free veterancy.
Is veterancy that important in this game? Should I take the time to learn the different bonuses of every units? Why?
Thank you.
I won't go over what's already been said but will give you a little comparison to show the potential effects.
I'd say the (arguably) biggest demonstrator of the effects of Veterancy would be LMG Obers at vet II/III.
The veterancy's combat bonuses do not make it obvious the big difference it makes unless you are familiar with the way the system works behind the screen so to speak. Eg: Elite Allied infantry such as (2x)LMG Paratroopers can walk over most axis infantry even vetted and even Obers at vet 0. At vet II that easy fight people expect suddenly turns into dropping models all over the place and low hp models running away on retreat are in serious trouble. A pair of Vet III LMG Obers can stand up to 3 or even 4 2xBren vet III tommies blobbed and inflict comparable bleed. You try that scenario with vet 0 tommies (to say replace a massive loss) and those Obers will just walk over you.
If I had more time I would do a video but unfortunately cannot.
Not all veterancies have the same effect or scale so a vetIII does not necessarily counteract vet III on another unit. That -29% received accuracy means that the enemy needs (1/0.71) -1 => 40.8% more accuracy to counteract. Very few Allied squads get +40% accuracy, tommies get +20% and Riflemen +30%. Cons get +40% but you'll lose to vet 0 LMG Obers with those guys potentially. Conversely, a +40% accuracy has more than counteracted most allied RA bonuses from vet so they are in an even more dangerous situation than if it was vet 0 vs vet 0.
tl;dr I'd suggest learning the more commonly used unit veterancies so you are less likely to be caught off guard.
