SD-15 Guide For Performance SpecificationsThis document provides guidance information on performance specifications focusing primarily on stating requirements in performance terms and ensuring that sufficient verification means are included in the specification to evaluate conformance. While the focus of this document is on defense specifications developed under DoD 4120.24-M, Defense Standardization Program DSP Policies and Procedures, the principles and techniques can also be applied to program unique performance specifications, performance-based purchase descriptions, commercial item descriptions, or any other type of procurement specification. This guide is intended to supplement the format and content requirements for writing performance specifications found in MIL-STD-961, Defense and Program-Unique Specifications Format and Content.

Performance Specification Guide SD-15

6.1   Intended use.  The Tactical Sling allows the Warfighter's weapon to remain in a ready position while conducting non-weapon firing-related tasks.

6.2   Acquisition requirements.  Acquisition documents should specify the following:

a.   Title, number, and date of this specification, and of all reference documents cited in

Section 2 and applicable documents from Section 6. b.   Requirement for design verification.

c.   Requirement for first article inspection.

d.   Requirement for conformance inspection. e.   Packaging requirements (see 5.0).

6.3   Additional Info.  Material described by this item specification is for a commercial off the shelf (COTS) product.  Supplier must have non-developmental production capability.

6.4   Ready Position.

6.4.1   High ready position.  The butt of the weapon is held under the armpit, with the barrel pointed slightly up so that the top of the front sight post is just below the line of sight but still within the gunner's peripheral vision. The non-firing hand grasps the handguards toward the front sling swivel, the trigger finger is outside of the trigger well, and the thumb of the firing hand is on the selector lever. To engage a target from the high ready, the gunner pushes the weapon forward as if to bayonet the target and brings the butt stock firmly against the shoulder as it slides up the body. This technique is best suited for the lineup outside of a building, room, or bunker entrance.

6.4.2   Low ready position.  The butt of the weapon is placed firmly in the pocket of the shoulder with the barrel pointed down at a 45-degree angle. The non-firing hand grasps the hand guards toward the front sling swivel, the trigger finger is outside of the trigger well, and the thumb of the firing hand is on the selector lever. To engage a target from the low ready, the gunner brings the weapon up until the proper sight picture is achieved. This technique is best suited for movement inside of building.
