Instead of 2x 60kg bombs it should get 2x Type 5 No.6 Mod 9 rockets
They have 230m/s velocity and 10kg TNT explosive mass giving them 62mm HE effect vs armour
How do they compare to the German 210mm Rockets?
German ones have higher velocity of 320m/s but bit lower explosive mass at 9.5kg TNT and 61.5mm HE effect vs armour
Japanese one is every so slightly better but more difficult to aim
