Well Patrick - I like the general idea, that one can test different build ups of units with the same scenarios. As long as the enemy will not behave in exactly the same way.
I will put my patience to the limit and let the clock run till 12 hours.
I finaly made it - taking me over 15 hours in game to complete!
You were right Patrick - the enemy main assault happens between 11 and 12 hours in game.
One odd thing - none of my helicopters could be put in defilade?
I am pretty sure that is one of the oldest scenarios in the game, put together before helicopter defilade was implemented. But I will check it when I am reunited with my programming computer in Iraq.
