Air carrier pilot reported GPS jamming caused by military doing broad and unannounced jamming operations led to the loss of GPS; and failure of ADS-B; clocks; terrain displays; and EGPWS during cruise near ELP.

Narrative

During cruising approaching ELP; lost position on both GPS receivers. ANP degraded as we approached El Paso eventually reaching approximately 0.5. Notified ATC our loss of GPS and ATC confirmed that jamming operations were being conducted in the area. Several other aircraft in the area also stated they lost GPS. A transponder fail light illuminated. Following the procedure I inquired with ATC on the status of our transponder; and as expected our transponder was still working full mode S but it was our ADS-B that was no longer working. UTC clocks; terrain displays; and Enhanced Ground Proximity Warning System (EGPWS) also ceased operation. To mitigate the loss of navigation performance; we requested to shoot a VOR approach to a runway that would keep us over the city of El Paso and away from terrain. This allowed us to navigate to a position to get visual contact of the runway and perform a visual approach. Upon landing some GPS functionality started to return such as terrain displays and the FO's clock.Caused by the military doing broad and unannounced jamming operations. Either the military adequately warns of such activity or cease them all together. Disruption of civilian air traffic into terrain sensitive airports is not acceptable.
