Give me a list of some US Army training schools
1) Airborne School: aka "jump school" is a three week course in which soldiers are trained to conduct airborne operations by jumping out of planes. A graduate of this school is commonly known as a paratrooper. 

2) Air Assault School: an approximately two week course where soldiers are trained in Air Assault operations, which includes movement in helicopters, rappelling from helicopters, and rigging gear to helicopters. 

3) Ranger School: a 62 day leadership course that if commonly viewed as one of the  toughest schools in the military with only an approximate 50% graduation rate. This is a small unit leadership course that includes but is not limited to patrolling, small unit tactics, mountaineering skills, airborne operations, etc. Only about 1% of the entire military has graduated from this course and is considered "ranger qualified"
