A number of security workers are experiencing the kinds of problems I have had for many years. Dry your eyes because a fund is made available to pay authorities to remove your pettiest & most infuriating problems. The only way law can be enforced, & crime in modern authorities.
Long term deployment
Is unlike contemporary engagement where extremity is dealt with by hardened men. There comes a point that comforts need to be restored, like a holiday from work for example, or depression & poor self care set in. So provision is necessary for unusual comfort from the outset & withdrawl. That means mountain gear not hikiing & parachute dropping of home comforts.
Soap
Is cheap, bury large amounts of it please. I have never tried washing with soil & rinsing, but it sounds harsh. Using soap improves the quality of life of near females, don't run out.
Symmetry
Makes encampments pleasant. Use a plumpline & spirit level at open or civilian areas. A groundsheet above tents keeps rain off & heat, a stone in the centre as you are aware collects water. Rain on a tent depresses.
