remembering the right name of the command unit ie. North Com) on the radar detection used by "Joint Task Force: Southern Border or JTF/SB... since this turned out to be a balloon allegedly and alot of our other ufo threads may be balloons.
Figure we'll be getting other military "UFO" leaks from JTF/SB eventually...
A small fraction of those, anywhere from 28 to 34 soldiers who are part of a 10th Mountain Division target acquisition platoon, are manning four radars across 2,000 miles of the U.S.-Mexico border to detect a growing number of drones that are suspected to be used by Mexico-based cartels. The commander of U.S. Northern Command told Congress in March that there are likely more than 1,000 drones spotted every month along the border.

The platoon operates Lockheed Martin's AN/TPQ-53 Quick Reaction Capability Radar, which is used in combat to detect rockets, mortars, and artillery.
"The Q-53 is traditionally counter fire or weapons locating radar, so we use those in a defense role so that if somebody fires a missile or artillery shell at us, we'll see where they shot from and where it's gonna land," Thomas said.
Upon arriving at the border, the platoon's radar was upgraded for small UAS detection and tracking "instead of just a ballistic flight path projectile," he said.

Soldiers are also using the AN/MPQ-64 Sentinel radar system which is used for short-range air defense and can detect hostile planes, helicopters, drones or missiles, according to RTX (formerly Raytheon). The difference between using the Sentinel in combat and at the border, Thomas said, is that they're "purely using this to find and detect" and not linking it to a Stinger missile or another weapons system meant to engage a threat.

Assigned to the Headquarters and Headquarters Battery, 10th Mountain Division Artillery, 10th Mountain Division, the radar platoon, led by Capt. Christopher McNamara, is part of the broader Joint Task Force-Southern Border mission. The team's primary role is to operate ground-based radars and feed critical intelligence to U.S. Customs and Border Protection (CBP).
....
Soldiers on McNamara's team operate two primary systems: the AN/TPQ-53 Quick Reaction Capability Radar, used to identify the origin and impact points of indirect fire such as rockets and mortars, and the AN/MPQ-64 Sentinel radar system, which tracks low-flying aircraft and drone activity across wide areas. Though originally designed for use on the battlefield, both systems have been adapted for homeland defense.
...
The team monitors radar feeds in real time and works to distinguish between benign and potentially dangerous activity. Radar interpretation relies heavily on operator judgment.
"It's not an automated system, so there is a human element to it," McNamara said. "We have to make determinations and distinctions about the data we receive and act accordingly. It can be difficult at times, given the sheer amount of data our system receives in a day."

A Research Associate Professor from UTEP further enriched the exchange by giving a brief about the Low Altitude Surveillance Program (LASP). LASP is the current program local civilian law enforcement use to track Unmanned Aircraft Systems (UAS), including drones. Due to the known threat of UAS during the southern border mission, military integration of LASP may provide more comprehensive intelligence reports to JTF-SB.
