This is a frequently discussed suggestion and here i bring it again.
There are 250+ (if i’m correct) of these over all factions and many of them between US and germany being notable squads with some popular history such as 101st airborne, 91st infantry division and 82nd airborne participating in operation market garden.
One of my main reasons are those, along with them having cooler squad icons i feel are the italian and british squads which are in short supply from what we have and ive even bought as much premium brit/italian that i could but still ache for more.
This is a fairly big relic of the older enlisted and rightly should return… not to mention the freedom of making actual squad lineups without having to spend minutes switching to X BR.
My way? Use the “code” from the battlepass shop to sell these squads through that interface and or bring a drop down menu for each class and tier in the tech tree example mg 1 bringing up all the legacy MG1 squads.
Could even be a feature earned after completing a nations whole tech tree.
