Phoenix Logs/UNSC Units/Jackrabbit
From Halopedia, the Halo wiki
Fast reconnaissance trike.
The Jackrabbit, or M121 Light Strike Vehicle, is a very fast scout vehicle that can detect cloaked enemy units and rapidly gather resources. It can be upgraded with a mini-frag launcher for some offensive punch, but is frequently used for exploration and liberating resource nodes from opponents.
Cheap and easy to manufacture, the Jackrabbit's design blueprint was one of the first to be integrated by the Spirit of Fire after Isabel's rescue. At first glance it looks like a lightly armored bike with a compact cockpit for the rider, but when decelerating the front splits into two separate wheels to form a tripod and retain stability. When bursts of speed are required, the two wheels pinion together automatically.
