        (DAMO-SWC) 22 SEP 90. SAS.
        1.        FIVE PROTOTYPE XM21 ARE AVAILABLE TO MEET DESERT SHIELD
        REQUIREMENTS FOR REMOTE SENSING OF CHEMICAL AGENTS. BASED ON REF A.
        ARCENT NEEDS TO KIJOW OPERATIONAL CAPABILITIES-OF THE XM21 PRIOR TO
        DETERMINING REQUIREMENTS.

        P. (U) THE XM21 IS AN AUTOMATIC SCANNING. PASSIVE INFRARED SENSOR
        THAT DETECTS NERVE AND BLISTER AGENT VAPOR CLOUDS ON A LINE OF SIGHT
        FROM 3 TO 5 I"ILOMETERS. IT CURRENTLY CONSISTS OF A TRIPOI] MOUNTED
        DETECTOR POWERED BY A THERMOELELECTRIC GENERATOR. SET UP AND
        OPERATED BY PERSONNEL WHO HAVE THE NEW EQUIPMENT TRAINING. IT SCANS A
        60 DEGREE ARC CENTERED ON THE PREVAILING UPWINZ DIRECTION. UPON
        DETECTION OF A TOXIC AGENT CLOUD, THE XM21 GIVES A VISUAL AND AUDIBLE
        SIGIIAL FOR THE li@TIATION OF PROTECTIVE MEASURES.
        3.        ORIGINALLY PLANNED FOR FIELDING SEVERAL YEARS FROM NOW. THE
        XMEI WDJLi3 BE ASSOCIATED WITH THE FOX NBCRS.    THE LSliC EXPRESSED AN
        URGENT NEED TO ACCELERATE FIELDING FOR DESERT SHIELD OPERATIONS AND
        WILL INITIALLY RECEIVE 5 TRIPOD MOUNTED XM2!.
S FOR THE XM21. ONE OPTION FOR
        EMPLOYMENT OF THE XM2! IS TO LOCATE THEM AT FIXE13 FACILITIE:; WHICH
        ARE CONSIDERED HIGHLY VULNERABLE TO LONG RANGE PERSISTENT (OR MIXED
        W17H N014-PERSISTEIAT) CHEMICAL ATTACKS. AIR FIELDS. al)r%T FACILITIES
        AND MAJOR ASSEMBLY AREAS COULD BE CONSIDERED PRIME TARGETS. OPERATIO14
        OF THE XM21 BY CHEMICAL RECONNAISSANCE PLATOONS WOULD SEEM
        APPROFRIATE.
        4.        AS A NEW ITEM. THE XM21 REQUIRES A E5 HOUR NEW EQUIPMENT
