If you take a look at the many different classes in Squad (and other games like Battlefield) you can see that all of them are special.
The Medic with his ability to heal. to have more bandages and to use them faster.
The AT´s with their anti-tank weapons.
The Combat engineers with his destructive abilities and building speed.
But if you take a look at the Riflemen he`s a bit... blank.
All he can do is being the Squad mule, he carries a bit of ammo which is quite important but its not enough.
So i would wish that he gets an upgrade, maybe that he can also carry more bandages (and maybe use them a bit faster then other classes but slower than medics).
Maybe a commander can use him to call in airstrikes or something.
Just make him more useful because as of now it seems more like a punishment for being the last one to join the squad and only being able to play the riflemen.
