In the last update the Japanese did just get a anti Tank Rockel launcher, but the Japanes arsenal is still very lacking in heavy Aircraft.
In New Guinea, the IJAAF used the aircraft in an anti-ship role, where the Ki-45 was heavily armed with one 37 mm (1.46 in) and two 20 mm (0.79 in) cannons and could carry two 250 kg (550 lb) bombs on hard points under the wings

I think a version of the Ki-45 Toryu with 2 x 250 kg (550 lb) bombs on hard points under the wings
would be best for the game in the attacker role, where Japan in Enlisted is very lacking
The B5N2 in the game now in BR2 isnt really good!
The Kawasaki Ki-45 Toryū (屠龍, Dragonslayer) would be i think a much better option!

This aircraft would be something like a BF 110 but for Japan, what Japan in the game really needs!
Another reason to ad dthe Japanes 705 th Air group hase just one aircraft the B5N2 what isnt realy good!
A different version of the Aircraft
Ki-45 Kai D (tei/丁)
Modified D, a modified Kai B, night fighter version, equipped with one 37 mm (1.46 in) Ho-203 cannon in nose and two fixed 20 mm (0.79 in) Ho-5 cannons in a Schräge Musik-style dorsal frontal position, and one 7.92 mm (0.312 in) Type 98 machine gun in the back position
without bombs i think !
