A fictional manned giant combat robot from the Gundam Mechaverse. It appears in Victory Gundam.
RGM-119 Jamesgun
The Earth Federation next generation succesor to the Heavygun Mobile Suit developed from lessons learned after The Crossbone Vanguard War. It uses a more advanced high output MS reactor, a Beam Rifle and the Beam Shield from the F91 Gundam.
The Jamesgun was an old unit by the time of the Zanscare invasion so it was relegated to limited rear guard use by the Federation far from the frontlines mostly.
This MS was succeded itself by the more capable Javelin.
