Artillery Target or Target Wide??

[DerBlitzer]

Yeah, use target wide if you've got boat loads of artillery rounds and have no idea where the enemy is, but figure he's probably advancing across a broad swath. It's more of a disruption tactic, as GoM said; unlikely to kill a lot of units, since it's not concentrated. Best used, I think, early in a game. It may also lead your opponent to believe that you've got LOS to lots of different places on the map. Once you know where the enemy has clustered, however, use regular Target.

But if you use Target Wide, make damn sure your own units are far far behind the spot, and not to the left or right. The rounds land across a very broad area, on a line roughly perpindicular to the target line (if I'm not mistaken). Not recommended for smaller maps.
