According to Reb Akiva Eiger
zt"l (Shu"t O.Ch.1:5)
food on Yom Kippur is
Muktza .
The Or Sameach argues and
holds since you can
feed the children on Yom
Kippur it is not Muktza.
According to Harav
R.Y.S. Elyashiv zt"l , food in
an army base located in an
unpopulated area
where there are no children,
is Muktza on Yom Kippur
