Recently, the Mustangs of the 4th Joint Communications Squadron (4JCS), Joint Communications Support Element (Airborne), put their skills, endurance, and determination to the test during their annual Mustang Challenge.
So, what is the Mustang Challenge?
It is a rigorous competition designed to evaluate Soldier readiness through a demanding series of events that test physical fitness, technical proficiency, military knowledge, and teamwork. Conducted during the Squadron’s two-week U.S. Army Reserve Annual Training period, this year’s challenge consolidated key Army and JCSE training requirements into three intense days of mission-focused competition.
The competition began with Weapons Qualification and a Soldier Board, challenging competitors to demonstrate both marksmanship and professional military knowledge. On day two, the pace intensified with Stress Shooting, where Soldiers were required to maintain accuracy, speed, and composure after navigating the newly implemented Combat Field Test (CFT). Competitors then transitioned to Land Navigation, relying on their map-reading skills, compass proficiency, and confidence to successfully maneuver across unfamiliar terrain.
The final day began before sunrise with an 8-mile ruck march, testing both physical endurance and mental resilience. Competitors then moved into a 24-hour field training exercise, where they demonstrated proficiency with high-frequency radio systems and conducted CN Team equipment validation. Throughout every event, the Mustangs displayed the adaptability, technical expertise, and determination that define the Squadron and contribute directly to mission success. After meeting with JCSE’s Element Command Team, 335th Signal Command (Theater) Commanding General and Deputy Commanding General (both were previous Commanders of 4JCS) paid the Mustangs a visit and joined in on the training right along side the troops! Probably brought back some fond memories of their time as Mustangs.
When the scores were finalized and the competition came to an end, one troop emerged on top. Congratulations to Lima Troop, the 2026 Mustang Challenge Champions, for earning top honors and securing bragging rights for the year ahead.
The Mustang Challenge continues to strengthen readiness, sharpen warfighting skills, and reinforce the culture of excellence that drives the mission forward.
Train Hard. Communicate Harder. Sound the Charge!
