8 man squads. For a snare they have one man banzai rush a tank with a satchel charge and blow himself up.
Actually, they could do 8 man squads like this.
When you build a Japanese squad you get two squads of 4 weak troops. They share veterancy across each other. Then you can get different weapon upgrades for each small squad, like lmgs on one and submachine guns on the other. Use them together to flank, etc. Would also keep with the axis theme of small squads to not fuck up single engagements too much.
