Enlisted
I've been having a lot of fun with this one, it's what Battlefield V wishes it could be and is Free to Play to boot. I also like how it's different in that it's main mode (and only one as of now because it's beta, 100 player battles have been promised) Squad Mode while only 10 vs 10 is still epic because each player is actually part of an AI squad of about 4-5 troops, watching the Soviets all charging in one big blob at the start of the match while roaring is breathtaking. You can also manage and equip your squads and as you progress you can unlock different types of squads, there is your basic infantry with just rifles, assault infantry, sniper squads, machine gun squads and so on, but from I've seen each squad can only have up to 2 snipers or 2 machine guns respectively and the rest of each squad is made up of troopers with rifles/carbines. Also you can get tanks and aircraft as "squads" too.
It is Free to Play though so where they try to make money is in buying equipment and weapons (individually) and new squad members (not that you ever lose any, but you can fill the empty spaces that are left in your default squads). But from my experience you don't "need" to pay, you can just play the game normally and get rewarded in-game cards or something that act as currency, and honestly I've been having fun without paying up.
Some people may take issue with the fact that your progress doesn't transfer over to other campaigns, the 3 of them being Battle of Moscow, Invasion of Normandy and Battle of Berlin (and more to come) with the each of them having a set of maps, but the more I play the more it makes sense because essentially each campaign is a different time and place in the war and you can only unlock things that are actually from that time period and place, so you won't be seeing any Panther tanks at the Battle of Moscow and in fact the default German tank of that campaign is the Panzer II and off the top of my head I think the last tank to unlock in this campaign is a variant of the Panzer III.
Really though, I had a lot of fun, finally a WW2 shooter I actually enjoy.
