Not that I do a lot of playing with the Japanese or tanks for that matter, but at least in a tank your bots are self contained and obey orders. Anyway, I figured out that a BR1 Japanese tank really shouldn’t be starting shit against a German tank. I’m sure someone can tell me what make and BR level the German tank is in this battle, but my guess is BR3?
Anyway, I come rolling up in my Ke-Ni low mileage one owner tank and peek around a corner and see the German tank, so I start shooting. I ended up firing 19 tank rounds into the German tank, and she was still rolling and the turret was still turning, but I could see a couple deaths. Finally, I’d had enough so I bailed from the tank and lobbed two explosion packs before she finally succumbed. Anyway, Japanese tanks, are insufferably weak. 
Tank of choice? Well, I only have three Japanese tanks, none are good, so choices are slim.
Confrontation begins
Explosion pack #2, success.
I did jump back in the weak ass tank and continued, although I literally had to hit enemy soldiers with the supposedly high explosive rounds to actually kill them.
So in conclusion, don’t take a low level pretend Japanese tank to a real tank battle, oh, and don’t do drugs.
