B. CAPABILITIES: THE GBCS-L ESM PROVIDES COMMUNICATION INTERCEPT
DATA AND EMITTER LINES OF BEARING IN THE HF, VHF, UHF, AND SHF
RANGES. IT IS CAPABLE OF ACCURATELY FIXING EMITTER LOCATIONS WHEN
USED IN TANDEM WITH TWO OR MORE SIMILAR SYSTEMS. THE GBCS-L ESM IS
ALSO INTEROPERABLE WITH LIKE SYSTEMS, INCLUDING THE GROUND-BASED
COMMON SENSOR-HEAVY (GBCS-H) AND ADVANCED QUICK FIX (AQF) SYSTEMS.
ADDITIONAL CAPABILITIES INCLUDE GEOLOCATING (IN CONCERT WITH OTHER
ASSETS) AND COMMUNICATIONS SIGNAL JAMMING (WHEN DEPLOYED WITH THE
GBCS-L ELECTRONIC COUNTERMEASURES).
C. EMPLOYMENT: THE GBCS-L ESM IS EMPLOYED ARMY WIDE FOR SPECIFIC
MILITARY INTELLIGENCE UNITS IN SUPPORT OF THE 2D ARMORED CAVALRY
REGIMENT AND AIRBORNE, AIR ASSAULT, AND LIGHT INFANTRY DIVISION
UNITS.
D. BASIS OF ISSUE: FOUR PER 2D ARMORED CAVALRY REGIMENT 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 HMMWV (M1097) BY
MEANS OF INTERCONNECTING CABLE AND HOSES.
F. TRANSPORTATION REQUIREMENTS: THE GBCS-L ESM IS TRANSPORTED ON
THE HEAVY-VARIANT HMMWV (M1097). AN ADDITIONAL HEAVY-VARIANT HMMWV
SUPPLIES BACKUP ELECTRICAL POWER AND AIR CONDITIONING AND TRANSPORTS
ADDITIONAL OPERATORS. 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: TWO 98G MILITARY OCCUPATIONAL SPECIALTY
(MOS) PERSONNEL ARE REQUIRED TO OPERATE THIS SYSTEM PER 8-HOUR SHIFT.
MINIMUM CREW SIZE IS SIX 98G MOS PERSONNEL.
(2) MAINTAINERS:
(A) UNIT-LEVEL MAINTENANCE: 31U, 33T, 52C, AND 63B
(B) DIRECT SUPPORT MAINTENANCE: 33T, 35E, AND 52C
(C) GENERAL SUPPORT MAINTENANCE: 39B, 44B, AND 52C
