Japanese infantry guns

[Mike Abberton]

I am not an artillery man by any stretch of the imagination, but it would seem like indirect fire support would require more than just a weapon that is capable of high(er) trajectory fire. You'd also need trained gun crews, trained forward observers, a communication network, and large® ammo trains. That last item might be important since the Japanese were very supply and transport limited overall. High angle fire would still be desirable in a direct fire weapon as a way to shoot over fortifications, over other low cover, and into trenches.

So, it's at least possible that the CS device is limited to direct fire because that's how the Japanese used it, rather than based on its stats alone. I seem to remember some previous comments and/or discussion that implied this was the case.
