When you set up a game in this manner you need to look at the ground in more detail. What cover, obstacles and distances are there to use or overcome. During my junior officer training days we learned to use COPPED to make basic assesments of the situation. The neumonic can be applied to the game board too. Think it through!
C = Cover for you and the bad guys, (what hexes are good to control)
O = Obstacles (rivers,swamps, hills - for some vehicles,etc) Select your lines of advance before you start moving
P = Positions of fire (how to use the ranges best) Remember to site weapons in pairs
P = Positions of observation (which in gaming comes from our birds eye view of the whole scenario)
E = Enemy, what is it you expect them to do and how does that influence your tactics
D = Distance = time, if I plan to flank do I have the number of turns required to make the moves or do I charge in
War gaming can be used to train the military mind.
What is the Aim?
What good and bad factors will affect the battle?
What courses of action do I have?
What is my plan?
Do this for each turn of the game and see if your results improve!
