11 bravo life and ranger school?

You will perform small unit tactics every day. But you will lead people at their very worst and at your very worst under the worst possible conditions. Everything sucks. Everyone will be tired, hungry, malnourished, weak, sleep deprived, grumpy, snappy, and constantly pissed off. You'll all be cold, wet, hot, sore, injured, and the rucks will he soul crushingly heavy. Sometimes well over a hundred pounds. When you think you couldn't possibly carry any more weight, your buddy will become a casualty and you'll have to carry their heavy ass ruck - and them - up a mountain or through a swamp.
That's the easy part. The hard part is when you're the one getting graded and not only do you have to do all that, but you have to lead everyone, make on the spot decisions under fire and in the pitch dark, and still maintain accountability of all of your people and their equipment after getting blown out of your patrol base or reacting to an ambush.

Hey man, it’s not that hard. You’re not in the field for 62 days. You’re not always hungry or sleep deprived.
Think of it as climbing Mount Everest. You have to hit those base camps to acclimate.
Same thing with Ranger school. The first FTX is two 3 day exercises. Mountain phase is two five day exercises. Florida phase is one ten day exercise.
In between they teach you what you need to. You have a bed, shower, food, laundry sand enough time to write letters.
Don’t let people make you think it’s some incredibly daunting task. It’s not easy, don’t get me wrong, but I graduated with an S1 clerk, a fueled, a PV2 from the national guard. You can do it man.

Training TTPs at Ranger school and at an infantry unit are basically the same (if you are in a decent unit). Ranger school is like an intensive program where they cram a year's worth of quality infantry training into 62 days... And students do it with a lot less sleep and not nearly enough food.
