In the current state of the game, there are six Soviet infantry units unlocking the same ability at Vet1 "Trip Wire Flares"
and it will soon go up to seven units with the same Vet1 ability, with the new Airborne Guards.
Replacing those Vet1 abilities at least for units from point 2 to 7, since they feel outdated.
Giving them some love by reworking their Vet1 abilities will create a sense of uniqueness for each unit.
I'm sorry that I can't come with specific abilities for each infantry unit at the moment, but I just wanted to point out what I consider to be an outdated ability spreaded through the entire army. Only Penal Batallions unlock a different ability at Vet1.
Ps: I know that there is a lot of work currently going on with the new Commanders about to be released, but It would be amazing if Team Relic could review these details.
