One of the required reading books for Marine Officers is:
- The Soldier's Load and the Mobility of a Nation
Book by S.L.A. Marshal
BGen Marshall either served, or reported from active combat actions: Poncho Via (Tex/Mex border), WW's 1 & 2 and Korea.
One of my favorite quotes is by BGen Marshall on Colonel Cole on what and when a Foreign Legionnaire will carry:
“By a series of calculations which need not be here explained, Colonel Cole has concluded that the individual weights carried within the legions were as follows:
1. Total for road marching 57.21 lbs/25.9 kg.
2. Total for approach march 44 lbs/22 kg.
3. Tactical load in combat zone 33 lbs/15 kg.”

S.L.A. Marshall,
The Soldier's Load and the Mobility of a Nation
As you can see, the weight has to do with the mission
1) Moving with all the gear necessary to set up a base camp with sufficient food for three days and ammo relative to the threat during the movement.
2. Must Have personal gear (peanut butter, chocolate, First Aid kit, dog tags and a spoon h/t WG. And, ammo sufficient for expected contact, or follow on action. Water and ammo make up the bulk of the weight. In my case a 5lb block of chocolate.
3. Ability to move, shoot and communicate as your unit closes with and destroys the enemy. Again, if what you carry doesn't support that necessity then you aren't carrying enough ammo and chocolate.
My son, also a Marine, served in both Iraq and Afghanistan (4 pumps). With the exception of infantry training, he never carried a full kit. (1) is replaced by trucks/helos. (2) Approach march relatively the same lbs/kgs. (3) Tactical movement...good boots, clean water and ammo sufficient for immediate contact. Additional by helo/airdrop. Don't ask for chocolate...it will be eaten by the aircrew before it arrives.
Now, we pilgrims have similar weight considerations:
1. Initial planning pack weight...57.21 lbs/25.9 kg. Must be including the "might needs"
2. Following Forum members painful comments and suggestions...44 lbs/22 kg. Come on...do you really need a two person tent (for you and your pack), iron skillet, extra boots, jackets, etc.
3. Prior to the initial trek from SJPDP to Roncesvalles (as an example)...33 lbs/15 kg. Not bad. Now, if you really think you still need that 2lb/4kg skillet and 5 lb / 2.26 kg camelback in addition to the three extra water bottles it's time to mail some things ahead. But not the 5lb chocolate bar. Remove the final "might needs" and your pack is now a respectable 26 lb/11.8 kg.
This thread made several comparisons among the varying loads carried by porters, servicemen and pilgrims. And, I submit all are wimps. Wise Individuals Making Proper Selections, based on their personal needs.
