The Empire of Japan's 16th Guards Battalion of the Imperial Royal Guard is a TSF unit of the Royal Guards. Apart from being some of the first troops to have deployed the Type-00 Takemikazuchi, pilots of the 16th Guards Battalion are regarded as the best of the best by their peers, and the unit as a whole acts as a training unit not unlike the IJA/MDF's Fuji Tactical Fighter Training Group.
In 1998, the 16th Guard Battalion acted as the rearguard for Imperial Japanese forces stationed in Kyoto, executing missions against the BETA until all forces had retreated. By the end of the 1998 BETA Invasion of Japan, the 16th Guard Battalion had only 8 TSFs left due to battlefield attrition; using eishi from the 2nd Guard Regiment, the ranks of the 16th were refilled, and the unit was quickly re-organized as a frontline Royal Guard unit to be ready for re-activation with new TSFs by 2000.
Prior to their combat action in 1998, the battalion operated Type-82 Zuikakus. As of 2001, the 16th Guard Battalion operates Type-00 Takemikazuchis. While they are usually deployed alongside the 2nd Guard Regiment in Kyoto as security forces for the Shogunate, it is not uncommon for the battalion to take a more active role in combat operations.
