What should I get??

I finally got the weapon gold order from the recent event and I am wondering which of the weapons should I get... I already got the conders MG which is perfect for my sweaty gameplay so I am wondering which one should I get for the US tech tree to fit in my other squad other than the free french squad. It can be anything from Br 3-5 it doesn't really matter because I got the stinger which I might use if your suggestions are good.

One last thing, if you have any Soviet suggestions, could you also suggest it as I might want to grind the soviets one day because it's a small tech tree with good guns.

Thank you and have a nice day ahead
