The two WWII Early War US Infantry sets. I got a lot of them and every time I get a chance I buy some more of them. I can't get enough. They are superb. The standing soldier with Montana Peak Hat firing his M1911 Colt .45 pistol is one of my favorites of all time. And the kneeling solider firing the M1919 Browning water cooled .30 caliber machine gun, in one piece! Such engineering!
Could be my favorite troops in my whole collection. I give honorable mention to the US Navy sailors for the early war period as well.
Can't wait for the new WWII US Army early war set to come out. Already saving up!
