Where this comes from: the publisher's own page for Buck, read October 12, 2026. The record fields, the ratings and the loadout are the publisher's. The prose on this page is ours: the ability is described here in our own words rather than reproduced, and the written biography and psychological report on the source page are not copied at all.

Illustration of a male operator in a grey knit beanie and white winter camouflage, firing the under-barrel shotgun of his rifle into a soft wall panel, splinters bursting outward — Original illustrationOur own composition of the operator, drawn from the character art the publisher publishes for him: the grey knit beanie, the reddish-brown beard, the grey-and-white winter camouflage jacket, the black plate carrier with its magazine pouches and the row of shotgun shells, the Canadian flag patch on the left upper arm, the round unit badge on the chest, the black gloves and the rifle with its under-barrel shotgun. The wall panel and the splinters are our own scene rather than a location in the game. This is drawn artwork, not a screenshot of the actual game, and not a photograph of a real person.

The Unique Ability

Skeleton Key is this operator's unique ability. What it does:

Buck's Skeleton Key is a 12-gauge shotgun mounted under his assault rifle with four rounds, letting him switch between the rifle and a breaching shotgun without changing weapons.

Loadout

The publisher lists the operator's weapons and gadgets as four groups. Two primary weapons and two secondary weapons are carried as alternatives, and the two gadgets are chosen before the round:

Category	Item
Primary Weapon	C8-SFW — ASSAULT RIFLE
Primary Weapon	CAMRS — Marksman Rifle
Secondary Weapon	Mk1 9mm — HANDGUN
Gadget	Stun Grenade
Gadget	Claymore
Unique Ability	Skeleton Key

Loadout: the publisher's own operator page, read October 12, 2026. A weapon's type is the publisher's own label for it. Where the publisher lists no type beside an item, none is shown rather than one being supplied.

The Record Fields

The publisher publishes a biography for each operator, and this page carries its record fields — real name, date of birth and place of birth — in the table at the top. The publisher's page carries a written biography and a psychological report beside these record fields. They are the publisher's own narrative text, so this page carries the record fields and links to the source for the rest.

Update Rule

Abilities and ratings change with balance patches, and this page tracks the publisher's own operator page rather than trying to keep pace with every adjustment. The date at the top records when that page was read, not when the game last changed. If a value here disagrees with the publisher's page, the publisher's value is correct and this page is out of date.
