"Floor disinfectant cleaner"
That had to be some bad stuff kernel, if hungry thirsty G.I.s would not touch it.

Damn I am getting old. But I remember when the "LRRP" Long range recon patrol rations came out.
Great idea, weight saver just add water.

Add a few critters of your choice, some green plants and you can last a long time with rice.
