Rally spot

The higher the level of your rally spot, the more troops you can dispatch at a time.

Use of a War Rally Flag item
(War Ensign) will bump this by an extra 25%. The 'Open Gate to Fight' option determines whether your army adds it's strength to the city defenses, or stays safely in barracks to leave the Wall defenses to take on an attack unaided.

March
This is where you assemble your armies and send them off to battle.

Exercise
The exercise screen allows you to pit hypothetical armies against each other to know what will win.

The best use of this offensively is to scout out the flat/valley/town you are going to attack then plug

the numbers received from your scouts into the 'Defender' side. On the 'Attacker' side (that's you) plug

in your available troops, then trim to slightly more than needed for victory. Doing this ensures victory

while leaving units in town to defend it from other attackers.

"''...what king, going to make war against another king, sitteth not down first, and consulteth whether he be able

''with ten thousand to meet him that cometh against him with twenty thousand? Or else, while the other is yet a great

way off, he sendeth an ambassage, and desireth conditions of peace." -Book of Luke 14:31-32 King James Version

Medic Camp
After every battle, whether against a city or a valley, a certain percentage of your casualties are wounded, the percentage depending on your level of the research "medicine". They can be healed here for some gold.

History
The rally spot in ancient society was a place where men of a tribe would gather and do rituals before they went out on a hunting trip. Likely these rituals and such were done to increase the morale of their tribe before going into war in hope that they'll be more efficient in their fighting. Also they were possibly ways of speaking to spirits or gods that these tribes believed in, ways to ask for help on the battlefield. The rituals were used in times of war between tribes, the warriors rallied for a parade or maneuver before they would go to war.

This place where they used to gather is the predecessor of the rally spot.
