Military operations around the world would surely like to back up every GNSS-based system with a $100,000 Cesium clock that has 1x10-14  stability, a $100,000 12-element CRPA antenna with a SAASM or M-Code receiver and a high-end INS with 0.01deg accuracy. Sadly, this is usually not a practical approach.
