Long range duels was where my Abrams did Ok. As you said, from across the river.
I had too many at one point and lost at least 4 in a single artillery pounding.
To those of you who know that equipment and instructions should be soldier proof, here was my take on bridge blowing and building:
Get a unit next to the bridge press the button and it will tell you which bridges can be blown. It should take 30 minutes.
So I decided to blow a bridge and a message pops up saying a bridge will be blown between 1105 and 1205.
Well that's over an hour away not 30 minutes I thought. Oh well.
It was only later when I put a bridge over the top right at 4205 of whatever that I realised 1105 was the hex reference not the time of bridge blowing !
