It’s a ground vehicle with no cannon for ground battle unlike all the IJN tanks you’ve mentioned which are equipped with tank gun or naval gun.
What can you kill with two torpedos in the ground battle ? Personally i don’t see the point in making a suggestion for it, at least as a ground vehicle.
I think within the framework of modern realities they will lack armor penetration even for a reserve position. You can, of course, make an ersatz SPAAG out of them, fortunately, among other things, these machine guns were intended to protect the vehicle from air attacks, but I’m not sure how appropriate this would be
from what I found out, the Type 93 13mm machine gun is already in the game and according to the sources I found, it had a penetration of 20mm at a distance of 500m https://wiki.warthunder.com/Type_93_(13.2_mm)
Look out for French reserve tanks, or just about any tank with a 2.0 combat rating. They are all simply invulnerable to this machine gun. In addition, the Ka-Tsu will have no advantage in armor, no advantage in size, no advantage in speed, or any other advantage over its counterparts.
therefore, a premium interesting vehicle of the 1st rank, for example anti-aircraft.the first m2 also has little armament, which is only the browning m2.
sorry for the crappy english
Is there any way to get the Japanese Ka-Chi? I really really really want this soo bad… i was away and taking a break from WT when they did this. When I saw it on youtube, it was too late for me to grind it…
