Yep. The First Edition is a legend. Excellent Artwork, very nice book. The rules were revolutionary that time. It`s a shame they got into the power spiral. Glad I have it on the shelf.

3rd or Ultimate Edition: Might look expensive, but IMHO well worth the price. About 3 times the thickness of the 1st. Ed. Background mostly intact and expanded, troops from 1st and 2nd ed. incorporated with some new added to the lists as well. Basic game mechanics are the same but enhanced to cover more situations.
The original "Infantry" could be used as Light Infantry but by the look the helmeted versions would be closer to the Heavy Infantry.
Chasseurs: Not as powerful as in the 1st ed. they are still a good and solid troop you can count on. Back than they were a bit of dissappointment as in RPG almost all Chasseurs we have seen wore heavy armour.
There are new Chasseur figs - more clothes but not that much armour.
The "armoured" Chasseurs were the "Enhanced Chasseurs" in the first ed too. Not the best of the figs, but gamewise very useful.
Check out the on-line store too!
