Before the war, in 1936, the 5th Battalion had been converted into the 45th (The Royal Warwickshire Regiment) Anti-Aircraft Battalion, Royal Engineers and had become part of 32nd (South Midland) Anti-Aircraft Group, 2nd Anti-Aircraft Division.
It transferred to the Royal Artillery in 1940 and later became a Light Anti-Aircraft unit and then an Anti-Tank regiment that saw action in the Burma Campaign, as part of 36th Indian Infantry Division.

Like the 5th Battalion, the 6th Battalion was also converted before the war, becoming the 69th (The Royal Warwickshire Regiment) Anti-Aircraft Brigade, Royal Artillery, transferring to the 32nd (South Midland) Anti-Aircraft Group, 2nd Anti-Aircraft Division, alongside the former 5th Battalion.

The 1/7th Battalion was serving with the 8th Battalion in the 143rd Infantry Brigade, both as part of the 48th (South Midland) Infantry Division.
The battalion departed for France in early 1940 to join the rest of the BEF.
The 1/7th took part in heavy fighting along the Ypres–Comines Canal holding the sector south of Houthem Belgium between 26 May 1940 and 28 May 1940: the heavy fighting between these dates allowed British forces to retreat towards Dunkirk.
Like the 2nd Battalion, the 1/7th was also driven back to Dunkirk, with the 1/7th having been reduced to 15 officers and 200 other ranks.
In October 1942, the battalion was transferred from the 48th Division to the 197th Infantry Brigade, serving now alongside the 2/5th Lancashire Fusiliers and 5th East Lancashire Regiment, part of the 59th (Staffordshire) Infantry Division, at the time serving in Northern Ireland.
The battalion served with the 59th in France during Operation Overlord, the Battle of Normandy, arriving in late June 1944 as part of the British Second Army.
The 59th Division was considered by General Bernard Montgomery, an officer who served in the regiment throughout the Great War and after, to be one of the best and most reliable divisions in his 21st Army Group.
However, the division was disbanded in late August 1944 due to an acute shortage of infantrymen in the British Army during that period and the units were broken up and used as replacements for other British divisions in 21st Army Group, as many had suffered heavy casualties.
The reason Montgomery chose the 59th for disbandment was merely because it was the most junior division of the British Army in France, being a 2nd Line duplicate of the 55th (West Lancashire) Infantry Division formed just before the war began.
Despite being overseas for only around five weeks, the battalion had suffered losses of 38 officers and 538 other ranks.

The 8th Battalion was also a 1st Line Territorial battalion and served with both the 2nd and 1/7th battalions in France in 1940.
After being evacuated at Dunkirk, during which it was reduced to 8 officers and 134 other ranks, the battalion spent many years on home defence anticipating a German invasion and remained in the United Kingdom for the rest of the war.
In 1944, the battalion became a training formation and a draft finding unit for forces deployed overseas.
In this capacity, it served initially with the 80th Infantry (Reserve) Division and later the 38th Infantry (Reserve) Division.

The 2/7th and 9th Battalions, both formed in mid-1939 during the doubling of the Territorial Army, were raised as duplicates of the 1/7th and 8th battalions, respectively.
Both battalions were assigned to the 182nd Infantry Brigade, 61st Infantry Division.
However, both remained in the United Kingdom throughout the war, both briefly serving in Northern Ireland until being reduced to reserve training battalions, with the 9th being disbanded in late 1944.
