BACKSTORY SETTING
The PA-S02 is an improved version of the PA-S01. Construction began at UC.0095, and UC.0096 was completed and entered service at La Vie en Rose. As the need for parliamentary security was no longer a core purpose of the design, the PA-S02 was designed as a wingman to the MTR-03S at the time of manufacture. It was accompanied by PA-S01s sent to La Vie en Rose as the leading mobile squad. The PA-S02 is fitted with the same core skeleton as the PA-S01 but with the addition of a power module in the feet and a modified knee design for increased defense and melee combat capabilities. The backpack uses the new Nu Gundam propulsion system. Compared to PA-S01, PA-S02's information sensing module has a smaller sensing range and fewer errors. Originally designed to use the same off-white color as the PA-S01, red was used for this MS as the nature of the mission changed, and pilots preferred it.

PA-S02 / UC.0106 During the Federal Provisional Parliament in Hong Kong, PA-S02 fought anti-Federation groups, and after the battle, the head and core cockpit of the PA-S02 were damaged, rendering it incapable of combat. The pilot was killed. The remaining parts were recycled as service spare parts for PA-S03.
