Tōma is the Sniper who has scored the most points with Eaglet, which is his only offensive Trigger, as as such he is Border's No. 1 Sniper. He also has the fourth highest score with any Trigger. Against Arashiyama Unit, he managed to snipe Tokieda in the head while Kitora and he were falling, and would have done the same with her moments later, still before either reached the ground, had Tokieda not interfered. During practice, he scored a headshot against Chika from 645 meters away while she was jumping out of a window. He was also capable of shooting through the moving, minuscule gaps among Alektor bullets that protected Hairein.
Satori's main Trigger that focuses on range, he is the only Border agent with two Eaglets in his Trigger set. This is due to his unique ability to utilize both at the same time. Furthermore, he has demonstrated to be capable of hitting a target while moving, and without using a scope. He generally ranks quite high during sniping practice, and his mastery is said to be top-class even within Border.
Twin Snipe (ツイン狙撃,Tsuin Sunaipu?): Satori summons two Eaglets and, after taking aim with one eye per scope, fires them simultaneously. This technique can be used against two different targets, or against only one for increased firepower.
Acrobatic Twin Snipe (アクロバティックツイン狙撃,Akurobatikku Tsuin Sunaipu?): An alternative version of Twin Snipe performed while the user is in motion and out of balance, Satori used it to kill a Trion Warrior while falling head-first, without using the scopes.
Narasaka is the Sniper with the second highest score with Eaglet, which suggests he is an extraordinary user. He is always seen ranking first during sniping practice. With this Trigger, his range is the highest in Border, and he is one of the only two agents capable of hitting an immobile target 1 kilometer away. Narasaka was also capable of shooting through the moving, minuscule gaps among Alektor bullets that protected Hairein.
As a member of a top tier unit, Oki is quite efficient in using Eaglet. With it, he was able to shoot off Yūma Kuga's arm while the latter was airborne from a fair distance, a feat not even some A-Rank agents can accomplish. He would also have taken out Chika Amatori while she was jumping off a building had it not been for her Shield. Oki first used Eaglet in Chapter 152.
Arafune's only Sniper Trigger is Eaglet, with which he is quite proficient. He managed to hit Lamvanein when the latter was flying, and to take out Chika immediately after she revealed her presence and despite the loss of both legs. With Eaglet, Arafune ranked 7th in stealth and target acquisition training.
Hokari is a very skilled Eaglet user. He is able to accurately snipe his targets in the head as soon as they come into view, as well as to support Arafune from behind without hitting him. He is also extremely fast at aiming. With Eaglet, Hokari ranked 5th in stealth and target acquisition training.
Hanzaki is known to be one of Border's best sharpshooters. He is one of the very few Snipers who would be capable of shooting through the gaps of Hairein's Alektor shield,[BBF Q82] and one of the only two who can hit an immobile target from 1 kilometer away. With his extremely high accuracy, he can easily hit the head of a moving enemy. With Eaglet, Hanzaki ranked 4th in stealth and target acquisition training.
As her primary main trigger, she is quite proficient in using it. With it, Hiura ranked 11th in stealth and target acquisition training. She's first seen using it in Chapter 107 (Episode 66 in the anime).
Although it is not one of the Triggers normally stored in his Trigger holder, Kizaki equips Eaglet when his ability as a Sniper is required. Since he was in charge of a group of Snipers, and is Chika’s mentor, it can be inferred that he is still very proficient with it.
Hatohara's exact level of skill with Eaglet is unknown, but Ema estimated her to be superior to Tōma and Narasaka, Border’s No. 1 and 2 Snipers. She was capable of shooting the opponent's Trigger without hurting them in the process. Hatohara is first seen using Eaglet during Ema's flashback in Chapter 108 (Episode 66 in the anime).
Chika consistently uses Eaglet during sniping practice, although she has never utilized it in Rank Wars. Her skill however is quite high, as in at least one session, she managed to place within the top 20. With her immense amount of trion, she can keep shooting it for more than 8 hours while wearing Bagworm, and still have energy to spare. It also increases her range. She replaced Eaglet with Hound after starting to use Lead Bullet.
Natsume uses Eaglet only during sniper practice, as her training Trigger is Ibis. Nonetheless, her progress with it has been steady thanks to Tōma and Ema's guidance, allowing her to rank 41st during normal shooting practice and 64th in stealth and target acqusition training,. She's first seen using it in Chapter 34 (but only in Episode 66 in the anime).
