When Lt Grayson formally reports to his regimental commander at Camp Shelby, he performs a complete salute before the commander even begins his. Proper procedure would be for Grayson to bring his salute up, wait for his commander to complete a full salute, then return his arm to his side.
Lt Grayson salutes his company commander while they are on the front lines in Italy. In reality, troops do not salute while at the front, since this identifies officers and makes them likely targets for the enemy.
In Italy, Lt Grayson's troops are fired on by two German soldiers positioned behind a broken wall on a high bluff. But rather than crouching behind the wall for maximum cover, they are standing. This makes them easy targets for Grayson's soldiers. Real snipers would have kept as low as possible behind the wall for maximum protection.
During the fire fight in the ancient ruins, a 61 mm mortar is set up behind a high stone wall. Had they been real rounds, they would have hit the wall above the soldiers' heads because the angle of the mortar was not great enough to allow the rounds to clear the wall.
Some of the German soldiers are seen wearing helmets of the style used in World War I.
During the battle in the ruins, the GI holds the mortar tube with his bare hands and fire around ten shells. At that time the tube would have been too hot to handle it bare handed.
