FIELD NOTES: Manufactured by StarCorps Industries and introduced in 2610, the latest Longbow was designed to address some of the problems with the original Longbow. The result was a faster, more effective ’Mech with improved heat dissipation and increased armor. Its weapons load out consists primarily of missiles, making the Longbow the heaviest ’Mech used in a fire-support role. It should be deployed with other ’Mechs for protection.
