Hmm...for me, I usually practice "last things, first in." So
usually, I put my spare No. 4 and socks into the ALICE pack
first...jacket on top of that..since I'm the signaller, I got my
dumb signal set, together with 2-3 spare batteries also...I usually
tear up up combat rations and distribute it to the sides of the
ruck, with maybe two packets of rice, some biscuits, and fruit bars
in the front pocket. I usually put another 2-3 canteens in my ALICE
ruck...usually with the top few items, like poncho, groundsheet,
hammock, I remember having the rifle cleaning kit in my left
pocket. Foot powder, toothbrush/toothpaste, camo facekit in the
right pocket. oh yes...and my chewing tobacco/cigarettes in the
left pocket too...together with the rifle cleaning kit..
