For the duty of seeking out those three German AT guns, I decided to chose only one of my three spotters. Not knowing their exact locations I also only selected onetube leaving two of my mortars for backup duty. My mortar was then ordered to use maximum duration of fire. After the bombardment I was very surprised learning that not only has the mortar crew spend all of their own HE but they have also spend the two other mortars ammunition leaving my two other spotters worthless! Can that really be correct - isn't that a glitch?
How should I've setup my bombardment in order to ensure that all three spotters were left some goodies?
