Attacking

[PoorOldSpike]

Here's an example of the 'Advance' order, basically it's often used if you want to gain ground without stopping, even though you might take more casualties.
It's late in the game so I 'Advance' my Russian inf across open ground (arrows on right) in a last push towards the flag, but the action is only a partial success because of heavy enemy resistance (including an arty barrage) and only a couple of squads get across.
