What makes a unit "a horse"?

This can't be true... can it?

Using the standard Rules.txt, it's easy enough to test. Entrench a phalanx on one mountain. Entrench a piker on another. Attack each with a Dragoons. Without a pike bonus, the Dragoons should win ~46% of the time. If the pike bonus works, the rate should drop to ~33%. You do need to test it at least 50 times, though. Don't have time to test it myself right now, but maybe later.

all this "horsing" is giving me a headache... ;(

were you refering to tagging tanks as pikemen? There's no reason why it doesn't work.
