3.3 Design. 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 IOTV subsystem (see 3.5) consists of

(1) One base vest assembly made up of a camouflage outershell base vest carrier with a ballistic insert set made up of removable ballistic (back and front) inserts, (2) One yoke and collar assembly made up of one each front and back yoke and collar carrier assemblies with a ballistic insert set made up of ballistic inserts (collar ballistic narrow back panels are removable), (3) One groin protector assembly made up of a groin protector carrier with a removable ballistic insert, ( 4) One lower back protector assembly made up of a lower pack protector carrier with a removable ballistic insert, and (5) One deltoid protector. Components are all attached to the IOTV. The IOTV 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 IOTV carrier to provide vital organs protection against multi-hits of small arms rifle bullets and indirect fire flechettes. The ESBI subsystem consists of a set of interchangeable, contoured plates inserted into left and right side pockets of the IOTV carrier. Webbing hanger attachments on the front of the IOTV outershell carrier 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 (see 4.4).

a) IOTV base vest only; which does not include any of the front and back yoke and collar, groin protector, lower back protector, deltoid protector or SAPI, ISAPI, ESAPI or XSAPI modular components.

b) IOTV base vest with one or more, or all of the modular components; front and back yoke and collar, groin protector, lower back protector, deltoid protector and/or one or two SAPI, ISAPI, ESAPI, or XSAPI

c) IOTV base vest 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

FQ/PD 07-05 B Page 10 of 56 is needed 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 3.5 Table VI-B).

Drill holes are not permitted.
