To close the gap with modern MS weaponry, the Flag Kai's offensive capabilities was upgraded. The standard linear rifle has been replaced by the GN Sword II Kai, a variant of the GN Sword II from the GN-0000 00 Gundam, and its missiles have been replaced by large smoke bombs. The sword is fixed as the "nose" of the craft in flight mode, allowing it to dogfight via the pair of beam emitters mounted on the top and bottom sections of the blade. When needed, the GN Sword II Kai can be used as a ramming device. In MS mode, the sword is hand-carried, again alternating between sword and gun for melee combat or short-to-mid range shooting. The weapon utilizes a GN Condenser to store a limited amount of GN Particles for beam firing. The large smoke bombs are deployed to create a massive smoke cloud to blind enemy sensors and allow the pilot to either flank the enemy position or to make a hasty retreat.
