I like all the dirty tricks you can pull with skirmishers. Don't you agree Andy Moss?
Send them on a long mission, block a forest track, scout a ridge, capture a leader behind enemy lines, shoot a battery in the flank getting a gun, overtack a unit to prevent it being pushed back (max counters), hmmm what else.....
Bill keeps removing them though which is a dirty trick in its own right
Their lower morale, reduced fire, reduced melee, zoc of killability, diffculty to rally and vulnerability vs cavalry make them pretty over rated though I think.
I Like it when my opponents leaves them lying around for some easy kills. I know Anton enjoys riding them down with a swarm of cossacks. The said force normally parades the shako's of the victims on their lances. Sometimes with the heads still in

.
Oh bit gross there chaps sorry.
