You tube is your friend.
But here are a few tips:
In Tank, to make it easier to get around, press down arrow and then circle you will change to commander view and circle makes you pop up, now you can see more of your tank, although you are vulnerable. ( On Allies you get a bonus mg to use as commander)
You can repair your tanks, but fall back from battlefield, give drivers two repair tool kits.
Always put your squad formation to wide, use square square and keep manually making your squad advance with you, but double tapping 10-20m or so ahead of you.
If you spot, everyone can see, great for planes and tanks, also your ai bots will point in the same direction.
Engineers can build spawn beacons, ammo boxes, anti aircraft gun, anti tank one too.
You can heal you winded squad members if you have a med pack, I carry two just in case.
When you start focus on all the xp trees in progress, it is tempting to increase squad size or who is in it, but in the beginning focus on XP, that’s how you get better and more weapons.
Planes need flaps added to ps5 controls, you are not flying a bf plane, you are flying a Warthunder flight model you have been warned.
There are 2 different campaigns, Normandy and Moscow which have separate xp branches, you need to level all your troops separately.
If you double tap square on enemy tank you can command your own squad to attack it, especially if they have Tnt.
You can pick up and throw grenades back, just press square and look at it, be careful!
That will do for now, enjoy!
