All I'm saying is that if you're using a very light (60mm or smaller) mortar – the sort that often has a strap instead of a bipod and no sights better than a line of paint on the tube – for what amounts to direct lay but you're relying on somebody else to observe the rounds falling and speak the very same corrections he would make by hand if he were the gunner, I'd treat that as a Forward Observer-Artillery task, not as a Gunner task. The downside would be having two rolls to fail; the upside would be the possibility of keeping your head down.

As for "What are you aiming at?", I find it hard to believe that an experienced mortarman couldn't dead-reckon a guess at the first shot and correct from there, alone or with a friend. The whole point here is to emulate irregulars (not artillerymen with grids and computers and fancy sights) conducting unplanned fire as a hasty ambush or assassination attempt. The mortarman blasts something in the general area of a target he peeked at earlier, his pal tells him what the results were, and they improvise from there. It probably isn't the Proper Military Way, but it seems a lot closer to what guerrillas or assassins would do.
