ΔE 19.5, loose: different enough that you should pick on purpose. Khaki Drill is a little darker, much more muted, warmer than Yellow Oxide.

Not as a straight swap; see the closer alternatives below. Loose match (ΔE 20). Khaki Drill is a little darker, much more muted, warmer than Yellow Oxide. They are different kinds of paint.
The same difference applies the other way round: Yellow Oxide is a little lighter, much more saturated, cooler.
ΔE is the colour difference between our two swatch estimates: under about 6 is close, over about 15 is loose. Real paints also differ in finish, coverage and how they thin, so test before you commit.
