Bullfrogs

The Bullfrogs was a nickname given to a squad of Orbital Drop Shock Troopers specializing in the use of jetpacks. During the Fall of Reach, they were stationed at New Alexandria, and helped SPARTAN-B312 capture an executive landing pad for use in the evacuation.

Trivia

 * On harder modes such as Legendary, the Bullfrogs are rather useless, they follow a set course of jumps, one of which carries them straight into the midst of Covenant with their backs to a drop, where they are usually quickly killed.
 * The Bullfrogs are the first official ODST's encountered in Reach's campaign mode. Chronologically, they're also "technically" the first ODST's encountered story-wise as well (excluding all the novels).
 * Despite being trained in the use of jetpacks, if a Bullfrog falls off of a platform they make no attempt to jump back up to safety, they instead fall to their deaths rather quickly. Because of this it is not unusual to have lost half of your fire team to falling by the time you have completed the mission.
