“Do not waste the lives of your troops” – General Eisenhower

Those are wise words indeed from General Eisenhower.  As stated in the Money Generation section, this game is about economics as much as fighting.  Dead units cost money to replenish, weakened units heal on their own and cost nothing to replenish. 

Never let a unit die.

That simple statement can not be over emphasized.  Give ground if you have to, but don’t let the unit die.  Retreat, replenish, and fight again.  When a unit dies, a player begins losing the economic side of the war.

“No soldier ever won a war by dying for his country” – General Patton

Well said Patton.  Dead units cannot fight.  Weakened units can be replenished and fight again.  Learning to control the units, and rallying them in order to fight again, is key to winning the game. 

If you are being attacked by overwhelming odds, pull a unit back, and let them get entrenched, or split your forces, and allow half to get entrenched, while the other fights.  Units can be replenished while getting entrenched. This allows you to give ground slowly.  Slowly giving ground gives you time to build more units to send to the fight. 

“We will constantly press the enemy with the full weight of our resources.” –  General Nimitz

On the counter side, if you find yourself in a position where you have the advantage in a battle, never let up.  Press on with all vigor, and always attempt to finish off a unit. 

“Show the enemy no mercy” – Major General Wingate

If you are able to kill the unit, then you have just cost your opponent money and forwarded position in winning not only the military aspect of the war but the economic aspect as well.
