Order of Battle

One of the major desisions you have to make is how to use your band in combat.
The smart thing to do is to make a basic Order of Battle (OB) and stick to that, making only minor changes as dictated by the opponent, the terrain and the scenario.

I like to have a OB consisting of a combined arms force inspired from infantry squad tactic as developed from world war II and later:
Assault troops AKA brawlers.
Close support troops.
Long range missile troops AKA snipers.

Assault troops (brawlers)

Primary function	Engage the enemy in closecombat.
Secundary function	Screen any close support troops from being charged by blocking any posible charge path.
Deployment	In cover on ground level. Preferably with a covered way to move forward toward the enemys softer models.
Battle orders	Move forward and take anyone OOA
Example	Possessed, flaggelants, warhounds.

Close support troops

Primary function	Stay close to the brawlers and shoot anyone that can charge one of your buddies.
Secundary function	Join melee when 'safe': choose opponets that are in combat with a brawler and only join if nobody can charge you back.
Deployment	Just behind a group of brawlers.
Battle orders	Folow the brawlers.
Example	Markman with blunderbuss and bow, elven ranger, a knifefighter with eagle eyes and perhaps trickshooter, a pistolero with a brace of pistols, pistoliere skill and perhaps eagle eyes/trickshooter.

Long range missile troops (snipers)

Primary function	Shoot enemy models that are a treat. Priority goes to anyone that treatens heroes, then those treatening snipers, then best target.
Secundary function	Get into places from where important parts of the board can be targeted. Making sure the enemy can't move freely without getting shot at.
Deployment	In cover high up with a clear view to important areas: Roads that offer long firing lanes; the objective if any such exist; places the enemy want to place models.
Battle orders	Don't move as long as there are anything to shoot at. Don't get into firefights where you are the underdog. Better to take cover or find somewhere else to shoot from. Stay out of closecombat.
Example	Elven ranger, markman with hunting rifel/handgun/crossbow/bow.
