Army Tests Electronic Warfare Tactics by Jamming Its Own Units

U.S. Army conducted electronic warfare exercises in which it deliberately jammed its own communications and navigation systems to test resilience and refine tactics.

Defense embedded with the Army's red team during the Ivy Mass exercise. Observers documented how jamming units targeted friendly forces to measure the impact on command, control, and movement. The red team used ground-based and airborne jammers to disrupt GPS signals and radio networks across multiple units. Data collected will guide decisions on training, doctrine, and equipment acquisition.

Army officials said the exercise revealed gaps in current procedures for operating under contested electromagnetic conditions. Units practiced alternative communication methods and navigation techniques when primary systems were degraded. The service plans to incorporate lessons from Ivy Mass into upcoming training cycles and procurement programs.

Specific systems under review include upgraded radios and GPS alternatives. >"The key takeaways will drive tactics and procurement going forward.
