Deceptive Deployment.
The deal is this: there are a number of armies where some bright fellow used a fancy trick of some sort to deceive foes about something having to do with deployment. We've got a good mechanism set up for this rule. It is not going to be a killer rule, but should add some fun for a few armies -- a bit of historical flavor and a fun rule, not a "Gotcha-you lose" rule. I'll give you four or five examples that have come up so far.
- The Murong Xianbei used women riding oxen, shaking bags of dust into the air, to simulate the movement of troops (probably cavalry) and deceive enemies. This is a case of a deployed dustbag women on oxen counter that can be swapped for an on-map deployed stand of cavalry, after deployment is complete.
- Agathokles of Syracuse, fighting (I believe) on the north coast of Africa, equipped a number of his camp followers and rowers with hoplite equipment to deceive his enemy (Kyrene, I think) into believing them to be hoplites. This is a case of one or two stands of Horde that can be swapped each for a deployed pair of hoplites (in rear support position).
- Both Caesar and Pompey (Marian Roman) equipped camp followers on nags and used them to deceive enemies into believing they had more cavalry then they actually did. This is a case similar to the dustbag women -- a deployed counter that can be swapped for a JavCav or Bad Horse stand, after deployment is complete.
- Yi Dynasty Korean infantry included a lot of pike with long spears. They also had a bunch of militia, equipped the same way but fighting much more poorly. Those troops would be very difficult to tell apart at a distance. Another case like Agothokles of Syracuse -- one or two stands of Horde that can be swapped each for a deployed pair of pike in rear support position.
- In the Breton army, a group of Saxons (fierce fighters, i.e. Warrior) were disguised with Breton clothing and haircuts and hidden among the Breton levy (Horde) as a deception against the Franks in a battle in 590 AD -- another case where the Horde swap could occur, after deployment is complete but before the battle starts.
