[paulo]

I was playing a battle in 1942, Russia vs Germany. I played the Russian side and chose to have 4 122mm howitzers. By turn 3 I only had 2 of them come up on the bombardment screen. For the rest of the battle only 2 were there. The other 2 were not destroyed or hit by anything. I'd appreciate any ideas on what might have happened. TIA
