From 1768 until 1805, a line regiment typically consisted of two field battalions – "Leib-" and "Oberst-" battalions – each of six fusilier companies; also, a grenadier division of two companies, which were normally detached to form composite grenadier battalions with those of two other regiments. In addition, it included one garrison battalion ("Oberstleutnant – Battalion") composed of four companies which served as a source for reserves at the regiment depot. The established strength of a 'German' line regiment in theory was 4,575 men, though this number was rarely above 2–3,000, especially in peacetime. With three battalions, 'Hungarian' regiments had a nominal strength of 5,508.
