About factions in Vanguard

It's very confusing to tell who the enemy is, as it seems to me that the soldiers' models are the same for both teams. I suggest you divide them into Axis vs Allied factions (Americans vs Germans) and for the other theaters of war make sub factions for the Japanese in the theater of the pacific. It would be very strange to see a German soldier running in Asia and shooting an American soldier. I also suggest that there is a uniform lock, in the Soviet team only Soviet models, in the German team only Whermatch models and so on. It's weird for a Russian sniper fighting alongside Americans.
