The Sichuan Thompson is plagued by the same problem the Sichuan SMG has, that being a small 5 man squad on br 3. A squad this small can hardly work in slightly more challenging games even on br 2 a squad like the Thompson 7.63 runs into the same issue. I suggest to increase the squads size to 6 by changing the current anti gunner to an assaulter and giving you a 6th normal soldier as either engineer or anti tank.
Problem is that you cannot recruit a normal Chinese soldier for USSR, so you would have a squad made of 5 Chinese guys and another who isn’t Chinese. So they should still give an event Chinese soldier, not a normal one.
I think all 5 men assaulter squads(Sichuan Thompson, 7.63 Thompson, Silenced MP40, Silenced Stengun )should be changed into max 6 men squad instead, i don’t use them because they are minus 2 men from a regular assaulter squads and it’s a huge disadvantage imo. A disadvantage severe enough that even their usual good SMG can’t make it up for.
