The Spotter (観測手(スポッター), Supottā, Lit. Observer ^?)^[1] position is one of the 9 official positions available to Border agents, one of the 7 directly involved in combat, and one of the 3 a C-rank trainee seemingly cannot work towards.^[2] The requirements to be classified as a Spotter are unknown, but Asumi Amakura, the only known Spotter (as well as the first spotter^[3]), is also the only one participating in Rank Wars who utilizes Enhanced Radar, possibly suggesting a correlation between said Trigger and the position.^[1] Since none of her Triggers seems to possess any offensive abilities,^[1] a Spotter may instead be any A or B-rank agent who has no Triggers capable of inflicting damage in their set, leaving the existence of a ranking specific to this position uncertain.

The duties of a Spotter are unknown. Asumi Amakura's Trigger set is geared towards detection, stealth-and-retreat tactics, which may mean her role is to keep track of the enemy's position.

Trivia

• In the military, a spotter is a member of a sniper team who detects, observes, and assigns targets and watches for the results of the shot, also accounting for atmospheric conditions.
  • This would be particularly fitting in Amakura's case, since one of her teammates is a Sniper and another is a Gunner equipped with Egret.^[1]
• When Viz first released their English translation of Chapter 206, they mistranslated the position as Supporter (サポーター, Sapōtā ^?); this was later corrected.
