My grandfather was a mortarman in WWII and he used to tell us how he planned trajectories in the heat of battle. Now, however, soldiers can punch in some coordinates and send a hot slug of death soaring straight at the enemy in a fusillade of metal. Much easier for the folks in the field, I think.
This new mortar, part of the Accelerated Precision Mortar Initiative, gives 10 meter accuracy at 11 miles. The mortar includes a programming wand to choose the exact landing location.
