Hackle

The hackle is a clipped feather plume that is attached to a military headdress.

In the British Army and the armies of some Commonwealth countries the hackle is worn by some infantry regiments, especially those designated as fusilier regiments and those with Scottish and Northern Irish origins. The colour of the hackle varies from regiment to regiment.

The hackle should not be confused with the much longer set of feathers commonly attached to the feather bonnet worn by Highland regiments (now usually only worn by drummers, pipers and bandsmen).

Modern fusiliers
In the modern British Army, there is a single regiment of fusiliers, plus a battalion of a large regiment. Hackle colours are:
 * Royal Regiment of Fusiliers: Red over white
 * Royal Highland Fusiliers (a battalion of the Royal Regiment of Scotland): White

Other ranks of the Royal Welsh; the regiment that was formed by the amalgamation of the Royal Welch Fusiliers and Royal Regiment of Wales, continue to wear the white hackle of the RWF.

Historic fusilier regiments
There were several other fusilier regiments which have been amalgamated and no longer exist. The hackle colours worn were as follows:
 * Lancashire Fusiliers: Primrose yellow
 * Royal Fusiliers (City of London Regiment): White
 * Royal Inniskilling Fusiliers: Grey
 * Royal Irish Fusiliers: Green
 * Royal Northumberland Fusiliers: Red over white
 * Royal Scots Fusiliers: White
 * Royal Warwickshire Fusiliers: Blue over Gold
 * Royal Welch Fusiliers: White

Non-Fusilier Regiments
Non-fusilier regiments which wear the hackle are:
 * Irish Guards (pipers on caubeen only): St Patrick's blue
 * Liverpool Scottish (now a platoon of A (King's) Company, King's and Cheshire Regiment): Royal blue
 * Liverpool Irish (now A Troop of 208 Battery, 103rd Regiment Royal Artillery): Blue over red
 * London Irish Rifles (now D (London Irish Rifles) Company, London Regiment): Green [Pipers wear St Patrick's blue]
 * Royal Irish Regiment (as the direct descendent of two regiments of fusiliers): Green
 * Royal Scots Dragoon Guards (on pipers' feather bonnet in Full Dress, pipers' / drummers' glengarry /atholl bonnet in No.1 and No.2 dress): White
 * Royal Welsh (Other Ranks only): White
 * Scots Guards (pipers on feather bonnet only): Blue over red
 * The Queen's University Officers' Training Corps: St Patrick's Blue (A Coy Caubeen Only)
 * Royal Air Force (pipe band only): Blue

Royal Regiment of Scotland
Following the amalgamation of the regiments of the Scottish Division to form The Royal Regiment of Scotland on 28 March 2006, the following hackles are being worn by the regiment's constituent battalions:
 * Royal Scots Borderers (1 SCOTS): Black
 * Royal Highland Fusiliers (2 SCOTS): White
 * Black Watch (3 SCOTS): Red
 * The Highlanders (4 SCOTS): Blue
 * Argyll and Sutherland Highlanders (5 SCOTS): Green
 * 52nd Lowland Regiment (6 SCOTS): Grey
 * 51st Highland Regiment (7 SCOTS): Purple

Whilst the white hackle of 2 SCOTS, red hackle of 3 SCOTS and blue hackle of 4 SCOTS have a known ancestry, the origin of 1 SCOTS black hackle and 5 SCOTS green hackle are not clear and have no apparent precedent. It may be that the black hackle of 1 SCOTS simulates the black-cock tail feathers originally worn in the 1904 pattern Kilmarnock Bonnet and latterly in the regimental Glengarry Cap by the Royal Scots and King's Own Scottish Borderers, who merged in August 2006 to form 1 SCOTS. Alternatively, it may be a sympathetic gesture to a former Lowland regiment, the Cameronians (Scottish Rifles), who went into 'suspended animation' in 1968 (and later disbanded), who wore a black hackle in their rifle green dress Balmoral. The adoption of the green hackle now being worn by the Argylls battalion (5 SCOTS) is no doubt a continuation of that regiment's association with the colour green, most prominent in the hue of their regimental kilts and stripes on their regimental association ties. (It is, however, worthy of note that in the 19th Century, all line regiments of the British Army used to designate their "light company" with a green hackle.) The Regimental Band of the Royal Regiment of Scotland does not wear the hackle. However, the Highland Band of the Royal Regiment of Scotland (Territorial Army) continues to wear the red hackle with the Tam o' Shanter. Tradition holds that the black hackle originated as a Scottish tradition of wearing a black feather in your hat to signify you have an ongoing quarrel with someone.
