In the footage, troops are clearly behind the lines, as they are operating from recently constructed berms. One soldier is likely operating a Leupold Mk.4 spotting scope on a tripod, while the soldier in front of him is pointing an LA-16U handheld laser marker. The spotting scope contains crosshairs that would give the observer the ability to watch and correct airstrikes by using markers in the crosshairs. The handheld laser marker, meanwhile, fires a laser that contains a four digit code, known as a pulse repetition frequency. The same code is also set on the supporting aircraft’s laser guided munitions, allowing the bomb to “see” the laser on the ground and guide itself into the target. Handheld laser markers are relatively new and are often not as accurate at longer ranges when compared with the larger laser-designating devices used by more conventional units.

Another piece of equipment is highlighted in the image above. The device, only slightly bigger than an iPhone, serves as a crucial node that allows U.S. forces to be effective observers for airstrikes without actually being in combat. The Remote Operations Video Enhanced Receiver (ROVER), which has been used since the mid-2000s, allows for overhead aircraft to transmit a video feed from their sensors to troops on the ground. The ROVER allows that feed to be funneled securely to another device, such as a computer or tablet. Older versions of the ROVER had a slight delay between the aircraft and the ground, forcing air controllers to use additional means to ensure they had real-time information before they were allowed to strike targets seen through the ROVER. The newer iteration, called the Tactical ROVER-p and seen in this link, is billed as providing real-time imagery.

Recent footage posted online over the weekend from news site France24, though, provides some insight.
