FIELD NOTES: The Catapult is a second line fire-support ’Mech used primarily by the Capellan Confederation military. Its design lacks the manipulative arms needed for effective close combat, so it requires front-line support to protect it. However, this heavy ’Mech can muster impressive firepower. Often refitted with Arrow IV missiles, the Catapult is excellent for a long-range support role.
