Availability of Jappanese artillery

[Mike Abberton]

IIRC, the 70mm and 75mm infantry are not even in the artillery box since they are not indirect fire units. So if you are talking about artillery greyed out in the box, your problem is not that they are direct fire Japanese infantry guns.

Typically, you get at least one "in supply" shot at the beginning of a scenario, i.e. most artillery is in supply on Turn 1. I don't think it can go out of supply until it fires once, and I don't think unloading can cause a change in supply, either. So unless the designer tagged the unit with low supply in the SCN file, I don't think the ammo level is your problem in the situation you described.

One possibility, if this is an amphibious landing scenario, make sure the artillery is not in the water. Artillery, direct or indirect, cannot fire from shallow water hexes. Move them to the beach. I have even seen a few scenarios where the designer forgot to put wagons (or trucks) on another barge, and the artillery was therefore useless. You can only unload the barge in shallow water, and you can't move the artillery out of the shallow water once it is unloaded.
