Cadets, Lieutenants, and Captains are not taught the death and scunnion you can inflict with mortars -- a heck of a lot more effect and range than 40mm grenades.
Today's generation of quad-carriers (Polaris, military Razor, John Deere, etc.) are the Mechanical Mule's modern descendants and are perfect for hauling mini-mortars like these in a Lightfighter environment.
Rest assured, the lessons are being learned and, especially with our current mission set, the value of mortars is not being underestimated.
After seeing our ability to effect the battlefield with 60, 81, and 120mm mortars while using a plotting board (two deployments worth of trying to get our LHMBC replaced), my detachment brought the lessons back to our Group. Mortar training throughout 5th SFG increased across the board in preparation for operations in Syria. With the advent of systems such as the M150 120mm and the RFSS the 120s play a huge role even in elements as small as 6-8 guys. We ran the M150 with 2 guys and were devastatingly effective. With snipers providing information on targets, relayed to UAV (COTS) operators, then to the mortar team, the ability to have 5 rounds on the way to the target before the first hits proved to be a game changer in the battle space. Then employing the UAVs to spot impacts, cross referencing with ATAK software (with constantly updated imagery), to provide to the meter corrections for the 120s enabled precision targeting of enemy elements.
Additionally, all members of the Detachment were trained on the 60mm mortar system. This enabled any one man to get behind the mortar and get rounds on target within a minute in the event of chance contact. Our operations were based soley out of Hilux trucks, and it is too easy to have a 60mm with rounds in the bed that anyone can run over and grab.
The video footage of the amount of devastation that can be brought to bear by a 8-12 man element is beyond belief.
