Regarding the mortar deviation I was about to just fudge the numbers to see what a hit looked like, but then decided to stay honest and look what happened. Does that make a mockery of the deep philosophical concept of karma? Indirect fire is definitely something I will be trying carefully again.
Jack, you seem quite adept at taking a set of rules and doing what you want to them, so I have little doubt any changes you make would be fine. At age 10 I was trying to use the Airfix guide rules which were dreadful. Rolling to see for hits. Then slightly wounded, heavily wounded. Keeping track of how many turns a figure was wounded for…trauma flashbacks.
I will have a think about that Sherman for the next game. I am glad you are enjoying a break from your regular wargaming with…different wagames.
