Reinforce
From The Evony Wiki ::The Free Forever Massive Multi Player Real Time Strategy Game
Reinforcing moves your troops from one town to another. This can be useful for defense or just to reallocate troops to a different town.
You can reinforce your allies towns by having them check the "Allows troops of allied members to garrison your current city" box in the Embassy (Only level 1 needed).
NOTE: Troops will use food of whatever city you put them up. Make sure you don't exceed your production in food. NOTE: These troops can only DEFEND. You cannot use the to attack.
- Important to remember in most cases the defending troops that are in the city and the ones in the embassy are stronger then the troops attacking the city. So, 100k archers goes along way in most cases. Although its also important to remember those troops need to be feed and if they die from starving or even getting attacked, you lose your troops.
