What's US' 82nd Airborne Division, which might parachute down on Iran?

The US is reportedly preparing to deploy troops from its Army's 82nd Airborne Division to Middle East amid war with Iran. The division's paratroopers can deploy within 18 hours of notice and are trained for airborne assaults including parachuting into hostile territory to secure critical infrastructure.
