> Know/practice rucking with 50kg for a 20km brisk walk (maintain speed 7-8 km/h) on uneven terrain, and no water (speak to your doctor first)

Ermm..... This is so far beyond basic militarytraining. Did you mean 5kg? And no water? There are special forces units that wouldn't be able to do this.

Full kit loadout is like 20 kilos, maybe 25-30 if you are the LMG/Nlaw carrier in your unit.

>Fast for 3-4 days (just to see what it feels like)(speak to your doctor first)

>Thirst for 1-2 days (just to see what it feels like)(speak to your doctor first)

No water for 2 days is MUCH worse than no food for 4.

> Water Yes. I can easily fast for 4-5 days once a month with no problem. Water, I've only done it a 3-4 times in my life, just to see how I react on it. I 'imagine' (not really) the scenarion of being in some country that is frequently earthquake-struck and being without access to water because of damaged infrastructure, etc. Again, the purpose is to know one's limits and _not_ to harm oneself.

How many people live in such zones where strong earthquake are frequent, and they have the real/possible risk of being trapped under some rubble for 1-2-3 days without access to food or water? Knowing your limits and not panicking helps.

>50kg What if you got a kid and you new to carry it for some distance? What if you have to kill an animal and bring it back to chop it and eat it? Again, the purpose is to do it a couple of times in your life to know what you can and cannot do. Not ruin your spine aimlessly.

2 days without water sounds completely idiotic. It could seriously affect your health.

The idea that everyone should do some basic military training is a good one, but the above seems focused on some over the top macho stuff.

Some basic first aid training however should probably even be taught in schools, and then repeated at least every decade.
