Every unit needs an aviation life support equipment (ALSE) shop technical library to keep the mission going. Without it, the mission can end before it starts.
All ALSE shops need equipment like helmets, vests, helmet bags, protective armor vests, tools and more. And the way to get your ALSE shop off the ground is to check out TC 3-04.10,
Aviation Life Support Maintenance (Jan 19), particularly Chapter 4.
