OK I am playing BFV again for a bit. Because of the 6 month break I don't know any of the new guns or what balance changes have happened. What is the good stuff right now for each class?
I don't have all the stats off the top of my head, but here's an overview, I bolded the weapons worth trying.
Assault:
Sturmgewher 1-5: It's the starter AR. It's pretty much just a budget StG 44. It gets the job done, but you'll want to upgrade to some of the later weapons.
Gewehr 43: Three shot kill with a decent RoF. You'll want to take the hip fire skills and drop mag to get the most out of it.
M1A1 Carbine: This is a semi auto that you can treat like an AR. Very spammable.
M1907 SF: A must pick for close range and close-medium. It has the fastest TTK out of all the assault weapons.
Turner SMLE: A well rounded semi auto. It doesn't have the same punch as the G43 (it's a four shot kill), but it makes up for it in RoF, mag size, accuracy.
StG 44: The most used AR. It's extremely versatile. A well-rounded AR.
Selb 1916: Three shot kill with a big mag and high accuracy; however, it suffers from the slowest RoF and terrible hip fire. I'd recommend the G43 over it.
Gewehr 1-5: A spammable semi auto with the largest mag. It's a cross between the M1A1 and Turner.
Ag m/42: A more accurate and controllable version of the M1A1, however, it has a smaller magazine.
Ribeyrolles 1918: This is an AR that you treat like a semi auto. However, you're better off going with a semi auto as long as you can control them.
MAS 44: An easier version of the Tuner SMLE, but with a smaller magazine. Learn to use the Turner.
Breda M1935 PG: The only burst fire weapon in the game. Great for closeish and medium range. It's next to useless for long range unless you put it on semi auto.
Karabin 1938M: A more accurate and controllable version of the G43, but it suffers from poor hip fire and long reload times. Use the G43.
Medic:
STEN: Starter smg and the worst in the game. You'll want to move on from it.
Suomi: It has the fastest TTK, but also the most recoil out of the smgs.
MP40: A better version of the STEN.
MP28: A weird hybrid. You're better of going the Suomi or M1928A1.
EMP: Similar to the MP40, but it has a higher RoF, while having less accuracy and control.
MP34: A smg designed for longer ranges. However, the Zk-383 outperforms it.
Commando Carbine: One of the bolt actions for medic. It has some weird accuracy and control, I'd recommend the M28 con Tromboncino before it.
M1928A1: Slightly less RoF (it kills in one less frame) than the Sumoi. However, it has much better controllability.
Zk-383: The most well rounded smg. You can spec it to be an all-around smg or you can spec it for longer ranges.
M28 con Tromboncino: Has decent hip fire and a grenade launcher. If you're going to use a bolt, use this one.
MAB 38: A well rounded smg, useful in most situations.
Support:
KE7: It's a decent starter weapon, however, there are LMGs the perform roles better.
Bren Gun: The most accurate and controllable full auto in the game. It destroys at medium and long ranges. However, it has subpar hip fire and a low RoF.
Lewis Gun: The most used LMG. It's the most versatile and well rounded out of the LMGs.
FG-42: LMG that you want to treat like an AR. Made for close and medium ranges.
LS/26: Similar to the FG-42, but it's more controllable and has a slightly less RoF.
I'm not going to go over the MMGs and shotguns. They play similar and you just use the one you feel comfortable with.
Recon:
P08 Carbine: Pick if you want to play aggressively.
I'm not going to go over bolt action and self-loading rifles. Again, they all play extremely similar and you just pick the one you're most comfortable with.
