Army replaces six legacy systems to automate lethal strikes
By Miriam Adler ·
Humans were reduced to active electronic signatures in a sensor-to-shooter link designed to collapse the distance between observation and lethality for division commanders.
The Intelligence Electronic Warfare Common Sensor (IEWCS) was designed to do one thing: collapse the distance between a signal and a strike. According to a program description mirrored by the FAS Intelligence Resource Program, this system was intended to provide targeting, detection, and location reports in "near real time" to division and brigade commanders. Most telling is its designed purpose to pass targeting data directly to TACFIRE in support of what the record calls a "sensor-to-shooter link."
In the clinical language of the military, this is efficiency. To a medical ethicist, it is the systematic removal of the gap between observation and lethality. When a human being is reduced to an "active electronic signature," the moral weight of the trigger is shifted away from the soldier and into the software of the sensor.
Spread Spectrum and Six Legacy Systems
Before the IEWCS, the Army's signals intelligence (SIGINT)—the gathering of intelligence by intercepting electronic signals—was fragmented. The public record defines SIGINT as the interception of communications between people or electronic signals not directly used in communication, often requiring cryptanalysis to unlock encrypted data. The Army's approach to this was a patchwork of "six separate and unique" legacy systems that the IEWCS was built to replace.
These systems were not just outdated; they were isolated. The FAS record notes that the legacy tools "lacked any meaningful degree of interoperability among themselves or with other Army battlefield systems." They were functionally similar but shared "virtually no commonality of hardware, firmware, or software." This fragmentation meant that the Army had to maintain different sets of operations and support personnel for each tool.
More critically, the old systems were blind to the evolution of the signal. They were "technically limited" in their ability to handle the frequency spectral coverage of newer emissions and advanced forms of modulation, specifically "spread spectrum." In the world of electronic warfare, spread spectrum is a way of hiding a signal across a wide frequency band, making it harder to jam or intercept. The Army's legacy tools were essentially listening for a shout in a room where the enemy had learned to whisper across a thousand different frequencies simultaneously.
A Sensor-to-Shooter Link
To fix this, the IEWCS consolidated these capabilities into three primary platforms. There was the AN/MLQ-38 (the Ground-Based Common Sensor-Heavy, or GBCS-H), the AN/MLQ-39 (the Ground-Based Common Sensor-Light, or GBCS-L), and the AN/ALQ-151(V)3 (the Advanced QUICKFIX, or AQF). The Marine Corps was granted its own version, the Mobile Electronic Warfare Support System (MEWSS).
These platforms were not merely listening posts. Each was equipped with modular subsystems for COMINT (communications intelligence), ELINT (electronic intelligence), and "electronic attack (EA)." This last term is the most sanitized part of the record. An electronic attack is not a physical charge; it is the use of electromagnetic energy to degrade or destroy the enemy's ability to use their own sensors.
When these systems were integrated, they replaced a specific roster of older tools: TEAMPACK, TEAMMATE, and TRAILBLAZER for ground-based collection; TRAFFICJAM and TACJAM for jamming and harassing communication links; and the helicopter-based QUICKFIX. The transition moved the Army from a set of specialized tools—some that only collected ELINT, others that only jammed—to a unified system where a single platform could locate, identify, and then attack a "threat critical node."
2010 and the Basis-of-Issue Plan
The rollout of this capability was phased. The GBCS-L arrived in fiscal year 1997, followed by the AQF in fiscal year 1998. The heavier GBCS-H was slated for fielding in 2002. Once the heavy versions were ready, the Army planned a redistribution: heavy divisions would upgrade to the GBCS-H, and the displaced GBCS-Ls would be handed down to light divisions.
The scale of the deployment was dictated by the "basis-of-issue plan" (BOIP). Under this plan, every division was to receive four AQFs. Depending on the unit's designation, they would also receive either four GBCS-L units for light divisions, four GBCS-H units for Armored Cavalry Regiments, or six GBCS-H units for heavy divisions. This ensured a persistent, 24-hour, all-weather tactical environment where "high value targets" could be acquired and processed without delay.
Other archives, such as the Internet Archive, contain references to related operations, including the "SWORD AND SHIELD" files regarding Warsaw Pact follow-on forces and later documents regarding multi-agent systems for airborne platforms. These suggest a broader trajectory of automating the battlefield, moving toward what the 2003 DTIC records call "Situational Awareness Management."
The FAS record concludes with a timeline for completion. Fielding of the IEWCS systems was to be complete in 2010.
