Carrying a load by using shoulder straps puts the weight of the load on all of the spine from the shoulders on down. This is both tiring and potentially causing back problems. A much better way to carry a load is to use a belt that's snug enough so that it can not slip past the hips and that also supports a rigid pack frame. Now the weight is supported by the belt. In this arrangement the shoulder straps are not carrying the weight, but rather are there to keep the load from falling backward.Comment by Geodkyt:
I( have removed links to photos on retailer web pages because they are not permanent links.
Alice clips are a key part of the system. They are the way to attach most things to a pistol belt.
|The Clip surrounds the belt. It does
not have anything to do with the eyelets in the pistol
belt. It will work with pretty much any belt.
|8465-00-001-0336 Belt, W.W. II vintage
marked LC-1 Eastern Canvas Products
The W.W. II Pistol belt had eyelets spaced 2 3/8" along the belt and 1 5/8" across the belt for attaching things like a canteen. The canteen had bent brass rod, maybe 1/8" diameter, that could be fitted into a pair of holes, either the top or bottom pair by removing the belt and bending it so the distance between the eyelets was small. Once the belt was straight the item attached could not come off the belt. This modern belt has the same eyelets for backward capability with that old system.
Why was the W.W. II belt an LC-1 and the new belt is an LC-2 (or what does LC-1 and LC-2 mean)?

In August there was a thread about the ALICE Pack frame on the Army Radios group. Jim Madden posted some photos that helped a lot in clarifying how the pack frame is used.

It's not clear to me if the following items are all ALICE or not. Also what's LC-1 and LC-2 mean? (probably Load Carrying #1 and #2, but what's the difference?)

5340-00-753-5581 Belt Keeper (ALICE Clip)
See patent 2869198 below.
I'm not sure if this is the correct NSN for the ALICE clip.
It can go over an object that's no more than 2 5/16" wide and 3/16" (0.1875") thick.
One layer of a ripstop belt is 2 3/16" wide and 0.230" over an eyelet and 0.145 over the material.
So you need to install the ALICE clip along the length of the belt where you want it since you can not slide the clip past an eyelet.
When opened, like in the photo at the left, there is some spring so you can open up the 3/16" to much more for installing the clip.
The shoulder straps on the Field Pack art too bit to allow ALICE items to be attached. I've seen large rubber bands used or other ways to attach stuff.

One end has a metal hook permanently attached by folding the strap upon itself and sewing.

Remove bladder and unscrew cap. Fully extend bladder by blowing into it. Float empty bladder on side, holding neck of bladder with 1/3 to 1/2 of opening under water. Do not totally submerge opening. Slowly submerge bladder as it fills. If bladder collapses, remove from water allowing air to enter and proceed as above. To hasten filling, use a scooping motion with opening partially under water. Insert correct number of water purification tablets as directed on tablet bottle. Note: capacity of canteen is two quarts.
To reduce sloshing noise of partially full canteen, squeeze to force water into neck and replace cap tightly. Wet the pile lining during hot weather to help keep water cool. Keep lining material dry during cold weather to provide limited protection from freezing.
Carry under the parka during cold weather to keep the water from freezing. Keep bladder and cover away from heat or flame.

The prior owner of this pack had used a pair of right shoulder straps in the released mode, with the bottom of the lower straps connected to "D" rings down low on each side of the pack thus allowing him to carry the pack using just shoulder straps and no pack frame. Although this was not the intention, the ALICE system provided the flexibility to easily complete this filed expedient setup.
The main compartment has a divider that appears to be designed to hold a radio. The PRC-104 fits nicely with either the small or large battery boxes attached. There's a strap and buckle that holds the radio into that packet. Either way you install the PRC-104 the strap ends up covering the mode and volume controls. If the AUDIO connector it near your right ear, then the handset cord will be convenient for Pedestrian Mobile operation. If the pack is dismounted and the radio used with the pack on the ground then the radio could be installed either way.
The main compartment is not too large once a radio is installed. The other compartment is 18" deep, just the right size to hold the AT-271 antenna, a counterpoise wire or other wires.
With a PRC-25 or PRC-77 installed in the pocket, the strap covers the frequency display window. A better design would be to use two straps each about 1/3 of the way across to hold the radio, and actually only use the one of them not blocking something.
When the Field Pack is hooked over the Pack Frame a Cargo Shelf in the upper position will add support to the radio, taking it's weight off of the pack cloth. This moves the radio up slightly and the pack closes properly. But is not compatible with tying the lower pack straps to the frame. To use the lower pack straps the Cargo Shelf needs to be removed.
By using the ALICE Pack and Frame the PRC-25, PRC-77 or PRC-104 can be carried in a more or less concealed way and all the accessories can be carried in the pack, so the CW-502 accessory bag is not needed as when the ST-138 radio carrier is used with the PRC-25 or PRC-77. PS Magazine for 1990 issue 451 shows the ALICE Pack Frame as a way to carry the PRC-25 or PRC-77 but does not mention this Camouflage Field Pack or when or why the ST-138 was discontinued.
The shoulder straps need to be installed so that they are not trapped under the Medium Field Pack. I.e. they need to be installed after the Field Pack is slipped over the top of the pack frame. The quick release on the right strap makes it easy to get it through the slit in the top of the pack frame pocket, but the left shoulder strap top strap buckle needs to be undone to get it installed properly.

This vest is designed to both carry the 40mm gernades and to also act as suspenders for the standard ALICE belt. It has built-in shoulder pads and a number of snap/velcro loops at the bottom to attach to the belt. One size fits all.
The MOdular Lightweight Load-carryng Equipment system may use a Velcro strap to replace the ALICE Clip, but I have not yet found a good technical description for MOLLE.

There are many reviews of the Rothco Canvas Water Bucket on Amazon complaining about all the water leaking out in 10 to 15 minutes. That would indicate they did not properly treat the fabric.

The oozing is controlled by the weight of the canvas.
"I am aware that the ordinary tin canteen has been envoloped in cloth or woolen fabrics, for the purpose of producing an evaporation from the outside when it is wetted; but this envelope soon becomes dry, and then the water in the canteen becomes warm and distaste ful; but with my canvas canteen the outside cannot become dry on account of the continual saturation from the interior."

This is the Lister Bag.
"Although devices of this type have been constructed of linen fabrics to form a fairly satisfactory device owing to the hydrophilic properties inherent in the natural resins contained in the linen fibers, a notable increase in cooling effect and more rapid wetting is accomplished by treating such fabrics with hydrophilic materials as disclosed hereinafter."
Quite a bit of the patent relates to choosing the fabric and coating.
"A cylindrical two-piece evaporative cooling water bag capable of retaining water substantially without seepage loss, comprising a round botton wall, and a cylindrical side wall of porous textile material, a hydrophilic substantially water-insoluble fabric-adhesive water-swellable polymeric coating on said textile material, said botton wall and said side wall having turned flanges and united together to form a substantially water-impermeable juncture between said bottom wall and said side wall; whereby leakage of water through said bottom wall and juncture is effectively stopped and evaporation of water through said side wall takes place at a Slow controlled rate without free flow of water So as to cool the water in the bag below ambient temperature."
