The 105 mm M2A1 (M101A1) howitzer was the standard light field howitzer for the United States in World War II. These guns were grouped into 4-gun batteries. Their role was to lay down a barrage to prepare for an advance, or to break the impetus of enemy infantry attacks.
Artillery of this kind could even slow attacks by armoured vehicles. With a range of 11,000 metres and a shell that weighed nearly 15kg, the 105mm gun was a formidable weapon indeed.
