multiple launch rocket system

Mobile artillery consisting of a TEL (Transporter, Erector, Launcher) vehicle (often a truck but can be a tracked vehicle) and a rocket pod capable of launching multiple guided or unguided rockets.

This tag however is inaccurate as "Multiple Launch Rocket System" refers specifically and only to the M270 Multiple Launch Rocket System, and similar systems are actually called MRL's (Multiple Rocket launcher's)
