A. DESCRIPTION: TRANSMITTING SYSTEM: GBCS-L ECM (GROUND BASED
COMMON SENSOR-LIGHT ELECTRONIC COUNTERMEASURES) LIN Z92763, BOIP
M084AA. THE GBCS-L ECM SYSTEM IS AN INTELLIGENCE AND ELECTRONICS
WARFARE ELECTRONICS SUITE MOUNTED IN AN ELECTRONICS ENCLOSURE ON A
HEAVY-VARIANT, HIGH-MOBILITY, MULTIPURPOSE, WHEELED VEHICLE (HMMWV)
(M1097). THE GBCS-L ECM NORMALLY WORKS IN CONJUNCTION WITH THE
GBCS-L ELECTRONIC WARFARE SUPPORT MEASURES (ESM) RECEIVING SYSTEM TO
PROVIDE COMMUNICATIONS SIGNALS JAMMING CAPABILITY IN THE MEDIUM
FREQUENCY (MF), HIGH FREQUENCY (HF) AND VERY HIGH FREQUENCY (VHF)
BANDS. THE GBCS-L ECM SYSTEM CONSISTS OF THE FOLLOWING COMPONENTS:

B. CAPABILITIES: THE GBCS-L ECM SYSTEM WORKS IN CONJUNCTION
WITH THE GBCS-L ESM SYSTEM TO PROVIDE COMMUNICATIONS SIGNALS JAMMING
OF A MINIMUM OF SIX DISCRETE SIGNALS IN THE MF, HF AND VHF BANDS.
THIS SYSTEM WILL REPLACE THE FOLLOWING IEW SYSTEMS AND THEIR
ASSOCIATED SUPPORT ITEMS OF EQUIPMENT: AN/TRQ-32A(V)2 (TEAMMATE) LIN
Z61894 AND AN/TLQ-17A(V)3 (TRAFFIC JAM) LIN C30675.
C. EMPLOYMENT: THE GBCS-L ECM IS EMPLOYED ARMY WIDE FOR
SPECIFIC MILITARY INTELLIGENCE UNITS IN SUPPORT OF THE 2D ARMORED
CAVALRY REGIMENT (LIGHT) AND AIRBORNE, AIR ASSAULT, AND LIGHT
INFANTRY
DIVISIONS.
D. BASIS OF ISSUE: SIX PER 2D ARMORED CAVALRY REGIMENT (LIGHT)
AND AIRBORNE, AIR ASSAULT, AND LIGHT INFANTRY DIVISIONS.
E. POWER REQUIREMENTS: THE SYSTEM'S POWER CONSUMPTION IS 10
KILOWATTS, WHICH IS PROVIDED BY THE HMMWV'S 400-AMPERE, 28-VOLTS,
DIRECT CURRENT ALTERNATOR. BACKUP POWER AND AIR CONDITIONING IS
PROVIDED BY THE GBCS-L ESM SUPPORT (CHASE) VEHICLE BY MEANS OF
INTERCONNECTING CABLE AND HOSES.
F. TRANSPORTATION REQUIREMENTS: THE GBCS-L ECM IS TRANSPORTED
ON THE HEAVY-VARIANT HMMWV (M1097). THE SYSTEM HAS ROLL-ON/ROLL-OFF
CAPABILITY FOR THE C-130 AIRCRAFT AND MAY BE SLING-LOADED BY CH-47
HELICOPTERS.
G. PERSONNEL/MAINTENANCE IMPACTS:
(1) OPERATOR: NONE. SYSTEM CONNECTS TO THE GBCS-L ESM
(BOIP M084AB, LIN Z62089)
(2) MAINTAINERS:
(A) UNIT-LEVEL MAINTENANCE: 31U, 33T, 52C, AND 63B
(B) DIRECT SUPPORT MAINTENANCE: 33T, 35E, 52C AND
68L (REQUIRED FOR THE CHALLS COMPONENTRY AND INTERFACE WITH THE
ADVANCED QUICKFIX (AQF) BOIP (M079AA))
(C) GENERAL SUPPORT MAINTENANCE: 33T, 35E, 39B, 44B,
AND 52C
H. SPECIAL NOTES:
(1) THIS SYSTEM IS APPROPRIATE FOR PUBLICATION IN AR
71-13.
(2) TEST, MEASUREMENT, AND DIAGNOSTIC EQUIPMENT (TMDE)
USED FOR THIS SYSTEM IS THE SAME TMDE USED IN THE AN/TLQ-17A(V)3.
(3) DOCUMENT SYSTEM IN THE SAME PARAGRAPH AS THE GBCS-L
ESM.
(4) DELETE ECM TEAMS PARAGRAPH TITLES IN THE TOE.
