Tropical Ruck & Frame – Details pt. 2

ADJUSTING AND WEARING RUCKSACK: The rucksack, with any type load attached, should be worn with the lower back strap positioned so that it fits comfortably on the wearer. To adjust the rucksack – adjust waist strap by shortening or lengthening so that it fits around the waist just tight enough so as not to constrict the clothing. Put on assembled rucksack and fasten strap. Adjust shoulder straps so that lower back strap fits comfortably.


Combat Pack: Place heavy objects near the frame, and sharp objects near the center so they will not rub against the bag. Use the side pockets for frequently needed items. Use side web hangers for attachment of canteen(s). Use side flap pocket for storage of maps, camouflage cover, etc.

Sleeping Gear: Sleeping gear and one poncho are normally rolled and secured above the combat pack utilizing the cargo straps.

Waterproof Bag Used for Upper Storage Bag: Where additional storage capability is required for loose items, sleeping gear and mission equipment or supplies, a waterproof bag may be utilized. Arrange items in the bag in such a way as to protect sensitive items from damage after the bag is positioned above the combat pack and secured to the frame by the cargo straps. Heavy items should be wrapped in sleeping gear or extra clothing, and centered above the combat pack to provide a well balanced load, and prevent damage to the rucksack or injury or discomfort to the wearer. This provides additional capacity to meet requirements and provides a built in CACHE capability. The bag can be removed from the frame by loosening the cargo straps and be readily disposed of if the situation so requires.
