2012 Infantry Soldier Silver Dollar
From the U.S. Mint website:
From the beginning, the Infantry has borne the brunt of sacrifice for securing and protecting the freedoms of our Nation, our friends and allies. It is the "boots on the ground," armed with both rifle and bayonet, and owns the last 100 yards of the battlefield. The 2012 Infantry Soldier Silver Dollar coin designs are emblematic of the courage, pride, sacrifice, sense of duty and history of the Infantry.
