The issues go straight back to the platoon sergeants and squad leaders. Once troops are placed on water discipline though it may seem excessive what needs to happen is that the troops are ordered to fill a canteen cup with water and drink it all down. when finished, they invery the cup and if any water comes out they get to drink another.
That procedure needs to be repeated as often as necessary by direction of medical personnel. If a medic is available he should be checking out the troops at the same time.
When a troop begins to become dehydrated they get less and less thirsty and drink less thus have to be forced to drink. I have been told that IDF requires an officer or NCO to witness piss samples of their troops. If the urine is bright yellow they are usually hydrated well. If the urine is a pale yellow to clear they need to be treated immediately. BTW they drink water till they can pee. Can get to be a chore but better than losing a trooper.
There's more to being a good NCO than getting to wear fancy stripes.
Thank you, I am sending your comments to my son.
Actually, it's the other way around.
The kidney has two functions: waste excretion and water balance.
If you have too little water on board, the kidney will secrete the waste (which gives the urine its color) with as little water as possible in order to conserve water thereby making the urine more deeply yellow.
If you have too much water on board, the kidney will secrete the waste with more water in it in order to get rid of the excess water thereby making the urine more dilute with a pale yellow or clear color.
If you want to prove this, drink a six-pack of beer and let us know if your urine turns darker or lighter. :-)
