The internal frame comprises two aluminum staves running the full height of the field pack. The staves are removable. The suspension system is adjustable allowing the user to position the field pack where it is most comfortable (The pastic height adjuster is sometimes removed during refurbishing and sewn in a fixed height position). The field pack has lower back padding as well as an extended lumbar support pad and the shoulder pads are made of bi-laminate foam. A softer, open cell foam is against the body for comfort followed by a stiffer closed cell foam for stability and good recovery after compression.
Two strap assemblies with quick release buckles allow for the attachment of the combat patrol pack atop the field pack when both packs are used together. When used in combination with either the ammunition carrying or tactical load-carrying vests, the field pack shoulder pads are worn over those of the vest, where they are retained by two one inch [ 2.54 cm ] pieces of webbing.

The combat patrol pack is designed for short missions and offers 1200 cubic inches of cargo space in two compartments. The main compartment is padded to protect the back from heavy, sharp items. The main compartment incorporates two tiedown straps that can be used to stabilize equipment such as a field radio. The combat patrol pack has a separate shoulder harness. When used in combination with either the ammunition carrying or tactical load-carrying vests, the combat patrol pack shoulder pads are worn over the vest shoulder pads, and retained for stability by two one inch [2.54 cm] pieces of webbing. The combat patrol pack can also be used in conjunction with the field pack.
The Individual Integrated Fighting System or IIFS was introduced in 1988 as a possible replacement for the All-Purpose Lightweight Individual Carrying Equipment in United States Army service. The IIFS continues to serve the United States Army to date, even though it is to be replaced by the Modular Lightweight Load-Carrying Equipment or MOLLE system. The Field Pack [NSN 8465-01-286-5356] and optional Combat Patrol Pack [NSN 8465-01-287-8128] are the "Existence Load Components" of the "Individual Integrated Fighting System". Serveral other components of the IIFS system exsist under the "Fighting Load Components" category.
