The Body armor, multiple threat model dismounted system is a modular vest protecting the upper torso from multiple ballistic threats which is easily configured to defeat predicted mission threat at a minimum system weight. The IMTV subsystem (see 3.5) consists of (1) one base vest assembly made up of an outer shell base vest carrier with a ballistic insert set made up of removable ballistic (front and back) inserts, and one set of shoulder straps, (2) one yoke and collar assembly with non-removable ballistic inserts, (3) one throat protector which attaches to the front base vest and collar with non-removable ballistic insert, (4) one groin protector assembly made up of a groin protector carrier with non-removable ballistic insert, (5) one lower back protector assembly made up of a lower pack protector carrier with non- removable ballistic insert, (6) one cummerbund assembly consisting of two interchangeable left and right sides, two interchangeable cummerbund adapters and one emergency release cable, (7) two side plate pockets, (8) one rifle bolster capable of being attached to either the left or right side of the front base vest. Components are attached to the IMTV. The IMTV provides protection from conventional fragmenting munitions and multiple hits from 9mm handgun rounds. The SAPI, ISAPI, ESAPI or XSAPI subsystem consists of a set of interchangeable, sized, and contoured plates inserted into front and back pockets inside the IMTV to provide vital organs protection against multi-hits of small arms rifle bullets and indirect fire flechettes. The Enhance Side SAPI and Enhanced Side Ballistic Insert subsystem consists of a set of interchangeable, contoured plates inserted into the side plate pockets worn inside the left and right cummerbund. Webbing hanger attachments on the front and back of the IMTV outershell accommodate limited load carrying compatible with MOLLE modular load bearing vest pockets. The variants of Body armor, multiple threat modular system configurations follow below. Recommended enhancements are encouraged to improve its operational effectiveness and manufacturability. a) IMTV base vest and cummerbund assembly only; which does not include any of the yoke and collar, groin protector, lower back protector, side plate pockets, or SAPI, ISAPI, ESAPI or XSAPI modular components. Attachment J.2 M67854-09-R-3000 9 of 82 b) IMTV base vest and cummerbund assembly with or without one or more, or all of the modular components; yoke and collar, groin protector, lower back protector, and/or one or two SAPI, ISAPI, ESAPI, or XSAPI and/or two Enhanced Side SAPI or Enhanced Side Ballistic Inserts. c) IMTV base vest and cummerbund assembly with none, some, or all modular components and limited load carriage using MOLLE pockets. 3.3.1 Patterns. The Government shall furnish patterns for the baseline design from which the contractor can use applicable parts to create cutting working patterns. Compliance with patterns is required to meet interface requirements with fielded personnel combat equipment. The working patterns shall include the size, directional lines, placement marks, notches, and provided seam allowances. Baseline patterns require a 3/8” seam allowance +/-1/16” unless otherwise stated on patterns. Except for the ballistic panels, all the components of the vest shall be cut with a tolerance of +/- 1/16” in accordance with the pattern parts indicated except where changes or enhancement(s) to baseline are proposed. The ballistic panels shall be cut with a tolerance of - 1/16”/+1/8” to ensure maximum protective area of coverage is achieved (see paragraph. 3.5, Appendix A, Table V-A). Drill holes are not permitted. 3.3.1.1 Base Vest and Components Carrier Outer Shell Item Nomenclature Computer Nomenclature Cut 1 BACK OUTER SHELL IMTV-BACK OUTER SHLL 1 2 FRONT OUTER SHELL IMTV-FRNT OUTER SHLL 1 3 FRONT OUT SHELL UPPER IMTV-FRT OUT SHLL UP 1 4 BACK LOWER FLAP IMTV-BACK LOWER FLAP 1 5 BACK UPPER FLAP IMTV-BACK UPPER FLAP 1 6 FRONT LOWER FLAP IMTV-FRONT LOWR FLAP 1 7 BACK SHOULDER HOLDER IMTV-BACK SHLDR HOLD 2 3.3.1.2 Base Vest and Components Carrier Inner Shell Item Nomenclature Computer Nomenclature Cut 8 BACK INNER SHELL UPPER IMTV-BACK IN SHL UPP 1 9 BACK INNER SHELL LOWER IMTV-BACK IN SHL LOW 1 10 FRONT INNER SHELL UPPER IMTV-FRT INN SHLL UP 1 11 FRONT INNER SHELL LOWER IMTV-FRT INN SHLL LW 1 12 FRONT SHELL INNER FLAP IMTV-FRT SHL INN FLP 1 13 TOP PLATE POCKET IMTV-TOP PLATE POCKT 2 14 BOTTOM PLATE POCKET IMTV-BTM PLATE POCKT 2 15 BACK FOAM POCKET IMTV-BACK FOAM POCKT 1 16 USE CARE POCKET IMTV-USE CARE POCKET 1 17 LOOP NAME TAPE REINFORCEMENT IMTV-NAME TAPE RNFRC 1 3.3.1.3 Base Vest and Components Plastic Item Nomenclature Computer Nomenclature Cut 18 FRONT FLAP PLASTIC IMTV-FRNT FLAP PLSTC 1 19 SHOULDER STRAP PLASTIC PLATE-SHL STRP PLSTC 1 Attachment J.2 M67854-09-R-3000 10 of 82 3.3.1.4 Base Vest and Components Ballistic Filler Item Nomenclature Computer Nomenclature Cut 20 BACK BALLISTIC IMTV-BACK BALLISTIC x 21 FRONT BALLISTIC IMTV-FRONT BALLISTIC x 3.3.1.5 Base Vest and Components Foam Item Nomenclature Computer Nomenclature Cut 22 BACK FOAM LUMBAR IMTV-BACK FOAM 1 3.3.1.6 Base Vest and Components Ballistic Panel Cover Item Nomenclature Computer Nomenclature Cut 23 BACK BALLISTIC COVER IMTV-BACK BLLSTC CVR 2 24 FRONT BALLISTIC COVER IMTV-FRNT BLLSTC CVR 2 3.3.1.7 Base Vest Inner Lining Item Nomenclature Computer Nomenclature Cut 25 FRONT INNER BIB IMTV-FRNT INNER BIB 1 3.3.1.8 Base Vest and Components 1.5” Webbing Item Nomenclature Computer Nomenclature Cut 26 SHOULDER STRAP BUCKLE IMTV-SHOULDER STRAP 2 27 SHOULDER STRAP YIBYAB IMTV-SHLDR STRP YBYB 1 28 FRONT SHOULDER BUCKLE IMTV-FRONT SHLD BCKL 4 29 BACK SHOULDER BUCKLE BACK SHOULDER BUCKLE 2 30 FRONT FLAP PULL BOTTOM IMTV-FRONT FLAP PULL 1 3.3.1.9 Base Vest and Components 1” Webbing Item Nomenclature Computer Nomenclature Cut 31 YIBYAB TEMPLATE IMTV-YIBYAB TEMPLATE 1 32 FRONT POCKET PULL TAB IMTV-FRONT PCKT PULL 1 3.3.1.10 Yoke and Collar Shell Item Nomenclature Computer Nomenclature Cut 1 UNDR COLLAR OUTER SHELL YOKE-UND CLR OUT SHL 2 2 YOKE BOTTOM SHELL YOKE-YOKE BTTM SHELL 1 3 YOKE TOP SHELL YOKE-YOKE TOP SHELL 1 3.3.1.11 Yoke and Collar Ballistic Filler Item Nomenclature Computer Nomenclature Cut 4 YOKE BALLISTIC FILLER YOKE-YOKE BALLISTIC x 5 BALLSTIC COLLAR WIDE YOKE-COLLAR WIDE x 6 BALLSTIC COLLAR NARROW YOKE-COLLAR NARROW x 3.3.1.12 Yoke and Collar Inner Lining
