Spotter

A Spotter 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. The requirements to be classified as a Spotter are unknown, but Asumi Amakura, the only known Spotter (as well as the first spotter), is also the only one participating in Rank Wars who utilizes Enhanced Radar, possibly suggesting a correlation between said Trigger and the position. Since none of her Triggers seems to possess any offensive abilities, 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 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.
 * When Viz first released their English translation of Chapter 206, they mistranslated the position as Supporter (サポーター); this was later corrected.
