=== ALICE and IIFS packs ===
In 1988, the US Army adopted a new [[internal frame pack]] system, a subsystem in IIFS. The design was based on commercial backpacks modified for military use with the addition of a special fighting vest and a detachable patrol pack. The original focus was to develop a load-carrying system for use in [[Cold-weather warfare|cold weather]]. However, in the end, the US Army decided the new internal frame pack would be the replacement for the external framed [[All-purpose lightweight individual carrying equipment|All-purpose Lightweight Individual Carrying Equipment (ALICE) system]]. Production and distribution started in 1990 but by 1993 it was evident that the new internal frame pack was unacceptable to a large number of combat personnel.<ref name=":4" /> 

Although a key problem with the internal frame was durability due to poor manufacturing, the IIFS pack system was also judged to have some basic design flaws. Based on a survey of users by the [[US Army Training and Doctrine Command]] (TRADOC), soldiers claimed the pack was too hot against the back in [[warm climates]], and was unstable and uncomfortable when heavily loaded. While many of the features of the system were liked (e.g., the patrol pack, and capacity of the main pack), it was judged not to meet the overall requirements of the Army. In spite of this rejection, most units surveyed (6 of 9), still favored having both load-carrying systems: the ALICE for warm and temperate climates, and the internal frame system for cold weather operations.<ref name=":4" />
