Design a military mech robot with tank-like tracks for mobility and a spherical cockpit. The cockpit, reinforced with armored windows, provides a 360-degree view for the pilot. The mech's body is bulky and angular, with thick metal plating for defense. It features two powerful robotic arms: one wielding a heavy machine gun, the other a missile launcher. Additional details include shoulder-mounted turrets, antennas, and exhaust vents, creating an imposing and combat-ready appearance.
