               DECISION MEMORANDUM FOR CC

               SUBJECT: Fielding of XMZI Remote Sensing Chemical Agent Alarm
               Prototypes @


               1.    (U) This is a Decision Memorandum. There is no suspense

               2.        PURPOSE. To obtain CC approval to field five XMZL
               Remote Sensing Chemical Agent Alarm prototypes into the AOR.

               3.        DISCUSSION.

                     A.        AVAILABILITY. Five XM21s are available for
               ARCENT. A two-man contact team can support training, maintenance,
               and employment of these systems. They're willing to remain in
               theater as long as necessary to insure successful XMZI
               employment. If team or user determine system doesn't function
               properly, or provide anticipated benefit, team will remove XmZls
               from AOR, Upon notification, team needs 3 weeks to arrive in
               country.

                     B.        CAPABILITIES. XMZI is a field deployable, passive
               Infrared sensor/signal processor that remotely detects nerve
               (G-Series) and blister agent clouds at line-of-sight distances out
               to 5 kms, It scans a 60 degree field of view in seven distinct
               segments within one minute. It proposes no health or safety
               hazard to operator or adjacent areas. System consists of a
               detector, tripod with accessories, transit case, battery cables,
               4(HN (24 V) lead-acid batteries, and a NATO adaptor for vehicle
               power.

                     C.        EMPLOYMENT. Employment concept for the XM21
               focuses on fixed site operations (ie. port facilities, maintenance
               depots, airports, etc) to minimize need for transporting the
ds to check XM21 periodically (ie.
               once every hour). System's central panel will inform operator of
               nerve or blister agent alarm and identify which fields of view are
               in alarm.

                     D.        MAINTENANCE, XMZls would arrive in theater with
               system support package (ie. spare/repair parts). Additionally,
               contractors would coordinate maintenance with USMC in-country
               maintainers, XM21s require monthly maintenance at DS level to
               check internal system alignment. Depot level repair would be at
               the contractor's facility in Florida.

                     E.        LIMITATIONS:

                          1.        System is fragile; must be restrained during
               transport. Best used at fixed sites.
