The recon bike is used as a hit-and-run vehicle, going into the battlefield to either harass slower armored vehicles or to finish off heavily damaged vehicles before retreating.
Recon bikes have low health and no armor, so they should never be exposed to enemy forces for long.
The recon bike is both small and fast, making it hard to hit.
Still, the bike has a measly 125 units of health and lacks armor, making it vulnerable to most attacks, even basic infantry weapons. A few shots from the ramjet rifle or the personal ion cannon will instantly pulverize it.
