Okay Commandos are tied for the 16th best veterancy instead of the 17th best veterancy out of ~20 infantry squads
Well Ranger get the same veterancy with Paras and even guards get bonuses of similar level...
(many elite infatry with high base stats do not get as high vet bonuses as other units.)
(For instance Osttruppen get better vet bonuses than grenadier but that does not make scale better )
Commandos used to have bad veterancy bonuses as many UKF units, but that was patched out. Relic had many units with low base stats get good vet bonuses and many units with high base stat have low veterancy bonuses.
I have read the argument that commandos "do not scale well" again and again and it simply does not hold water. It is simply a myth to downplay commandos and present worse than they actually are.
The unit has powerful bases stat and its veterancy bonuses are inline with other elite infantry like Paras/Ranger.
Commandos are a cost efficient unit and very difficult to kill once they reach vet 3.
