Why can vehicles only be pinned by indirect HE fire? Because if i allowed them to be pinned generally,then the rules would be simpler, and I couldn’t have that, could I? 🙂 For the rules above, I was basing them on my battalion level rules where 1 vehicles represented 3-6 and so pinning a troop of tanks did not make sense and was too much of a penalisation. I carried this over to the 1:1 rules above. I have changed my stance since then and in the name of simplicity vehicles and infantry are effected the same by fire (for my 1:1 rules and my 1:5 rules).
