The 172nd Infantry was one of the three regiments in the 43rd Infantry Division in WWII. In peacetime this was a National Guard division from New England. Like all National Guard divisions called into active service for WWII ("Federalized"), it received infusions of men from all over and lost much of its flavor as a state-based National Guard unit. The division fought in the Pacific, in New Guinea, the Solomon Islands, and on Luzon in the Philippines Islands. See the link below for a more detailed WWII history.

Not in WW2. Before 1939, each US Army Infantry Division had 4 infantry regiments. This proved to be too large for use on the battlefield. So the size the division was reduced and one regiment was removed. So the 3rd Infantry Regiment could have been part of a Division before then. However, during WW2 the 3rd Infantry Regiment was not part of an infantry division. Source: http://www.custermen.com/ItalyWW2/ArmyOrg/OrgChart/Divisions.htm
