Re: The best place to put your range units
It depends on the circumstances for me too, and LuckyPistol made a good point about the kind of ranged units you have.
I like having skirmishers on the wings if I can, but I usually keep them behind a melee infantry line because they're usually skirmish infantry and I worry about enemy cavalry.
As twgamer said, one downside of putting skirmishers behind melee infantry is that it takes longer to move them to the wings. Also, when the enemy use skirmishers as their front line, they may be able to shoot at the player's melee front line before your skirmishers get within range.
