Armor Main Gun Ammo Load Question

[jomni]

Most probably default depends on the potential enemy threat for the scenario.
If infantry heavy... HE.
If tank heavy... AP.
But that's just my suspicion.
I always make sure to check the ammo for all support weapons and ammo at the start.

By the way, here's a tip for Vietnam and Afghanistan players:
Make sure to use CAN for you grenade launchers when firing at enemy 1 hex away, it does wonders. Switch to HE when more than 1 hex and it also enables you to do indirect fire.
