Game Mechanics - Campaign Map - Land troops | Campaign Map Empire: TW Guide
Last update: 11 May 2016
You can gain some advantage by controlling your troops on the campaign map. First of all you must remember that armies must be close to each other. Keep them in their reaction zones marked with green lines (look at the picture below). As a matter of fact when one army will be defeated the others can come with aid very quickly.
Remember to replenish your regiments after each battle. The most experienced troops can be combined (marked as red on the picture below). You can call some reinforcements to the less meritorious . As a matter of fact you will get some very good regiments and more of troops that have to gain some experience in the next battles.
There is no sense in attacking enemy harbors, factories, farm etc. The first thing is that it is better to take control over the area that can produce goods. In addition computer controlled player will get money for free (even when the are not producing or selling anything). You cannot harm them in that way then.
Remember that your army can attack trade routes too. However moving on the enemy territory is connected with the willingness to take control over some new areas. As a matter of fact, the possibilities of blocking trade routes will be extremely rare.
