The following article on D-Day regiments is an excerpt from Barrett Tillman' D-Day Encyclopedia.
American D-Day Regiments
In the U.S. Army an infantry regiment was composed of three battalions, each with three rifle companies, a headquarters company, and a heavy weapons company. In early 1944 personnel strength was typically 150 officers and three thousand men. An airborne regiment consisted of 115 officers and 1,950 men. By 1944 U.S. armored divisions had three tank battalions rather than the previous two regiments. An armored battalion typically possessed forty officers and seven hundred men, with fifty-three Sherman medium tanks and seventeen Stuart light tanks.
The infantry regiments assaulting Utah and Omaha beaches were:
- First Division: Sixteenth, Eighteenth, Twenty-sixth Regiments (Omaha).
- Fourth Division: Eighth, Twelfth, Twenty-second Regiments (Utah).
- Twenty-ninth Division: 115th, 116th, 175th Regiments (Omaha).
Airborne infantry regiments descending on Normandy were:
- Eighty-second Division: 505th, 507th, 508th, 325th Glider.
- 101st Division: 501st, 502d, 506th, 327th Glider.
British D-Day Regiments
The regimental system was deeply ingrained in the British army, with some units tracing their lineage back three hundred years. For instance, the King's Own Scottish Borders in the Third Division had been established in 1689. However, owing to varying overseas service and the inevitable need to mix and match for specific operations, few British regiments fought as such. The situation was further complicated by the fact that many regiments possessed only one or two battalions. Consequently, a British brigade usually was of regimental strength, with unrelated battalions serving together. In 1940 a full-strength British infantry brigade consisted of seventy-five officers and 2,400 men.
The following British and Canadian regiments landed on Gold, Sword, and Juno beaches:
Third Division: Eighth Brigade (First Battalion, Suffolk Regiment; First Battalion, South Lancashire Regiment; Second Battalion, East Yorkshire Regiment); Ninth Brigade (First Battalion, King's Own Scottish Borderers; Second Battalion, Lincolnshire Regiment; Second Battalion, Royal Ulster Rifles); 185th Brigade (First Battalion, Royal Norfolk Regiment; Second Battalion, Royal Warwickshire Regiment; Second Battalion, King's Shropshire Light Infantry).
Fiftieth Division: Sixty-ninth Brigade (Fifth Battalion, East Yorkshire Regiment; Sixth and Seventh Battalions, Green Howards); 151st Brigade (Sixth, Eighth, Ninth Battalions, Durham Light Infantry); 231st Brigade (First Battalion, Dorsetshire Regiment; First Battalion, Hampshire Regiment; Second Battalion, Devonshire Regiment).
Third Canadian Division: Seventh Brigade (Royal Winnipeg Rifles, Regina Rifle Regiment, First Battalion Canadian Scottish Regiment); Eighth Brigade (Queen's Own Rifles of Canada; North Shore, New Brunswick, Regiment; Le Regiment de la Chaudière); Ninth Brigade (Highland Light Infantry; North Nova Scotia Highlanders; Stormont, Dundas and Glengarry Highlanders).
Sixth Airborne Division: Third Parachute Brigade (Eighth and Ninth Battalions, Parachute Regiment; First Canadian Parachute Battalion); Fifth Parachute Brigade (Seventh Light Infantry Battalion; Twelfth Yorkshire Battalion; Thirteenth Lancashire Battalion); Sixth Air Landing Brigade (Twelfth Battalion, Devonshire Regiment; Second Battalion, Oxfordshire and Buckinghamshire Light Infantry; First Battalion, Royal Ulster Rifles).
German D-Day Regiments
By 1944 the German army fielded several types of infantry and armored divisions, and therefore different types of regiments. There were maneuver regiments and static (defensive) regiments, plus panzer, panzer grenadier (mechanized infantry), and parachute regiments. A representative infantry regiment had forty-five officers and 1,800 men, while a panzer regiment typically had seventy officers and 1,700 men, with a battalion of Mark IVs, and a battalion of Panthers. Panzergrenadier regiments might field ninety officers, 3,100 men, and 525 vehicles. The authorized strength of parachute regiments closely resembled grenadier units-ninety-six officers and 3,100 men.
However, all the foregoing figures were according to formal tables of organization. In reality the German army fought understrength and with less equipment than authorized at least from 1942 onward.
