there's going to be thousands of dead people, cats, dogs, etc, all over the place, which makes a helluva disease vector, on top of the waste. Nobody is going to be digging latrines when people are shooting at everyone they see, in the hopes of taking the guy's gear, or even to eat his flesh. I'm going to be below ground. Pee into a large mouthed bottle, solid wastes into the soil in the corner. Each night, dig up and bag/bucket the latter, take all wastes out and dispose of them, along with getting more water. Then back into the hole for another 24 hours. It will take a year for most of the fighting and diseases to pass by, but the Viet Cong lived like that for THIRTY YEARS, not just one year. Read a book, THE TUNNELS OF CU CHI. Also read MY THIRTY YEAR WAR, by the last of the Ww2 Japanese "holdouts".
