The order of battle tab allows you to browse and locate each formation under your command.
The 35th Tank Battalion. When the HQ unit of the battalion is selected in the map, the command structure is shown as a series of lines (green lines connecting to subordinates, blue lines connecting to units up in the command structure).
This is the 51st Armored Infantry Battalion.
This is the 1st Battalion, from the 318th Infantry Regiment. These are foot troops with limited mobility but with great ability to infiltrate behind enemy lines.
Indirect fire support ... don't forget the important role of artillery in the battlefield. We have two battalions of self-propelled artillery (around 28 guns each). I have clicked on the unit icon to see a picture of the actual vehicle.
Last but not least, reinforcements. This information is available from the reinforcements tab ("Reinf"). We will be reinforced on day 2 by one armored brigade and on day 3 by another armored brigade.
