For the US Army, it's a bronze oak leaf. The same insignia is used by Majors in the Air Force and Marine Corps, and by those holding the rank of Lieutenant Commander in the Navy and Coast Guard while wearing certain uniforms.
No
The rank typically associated with the gold leaf insignia in the army is that of a Major.
No, there is no rank of commander in the Army. In the Army commander is a title, not a rank. In the Navy, there is a rank of Commander, it is the equivalent of Lt Colonel or O-5.
Very basically speaking, the difference is one step in rank. While a Lt. Colonel is normally referred to a Colonel, a Colonel is sometimes to referred to as a "full bird colonel" to distinguish the difference. In the Army at least, a Lt. Colonel wears a clover leaf rank insignia (silver, I think) but a full Colonel wears an eagle insignia, hence the reference "full bird."
Lieutenant Colonel insignia is identified by a Silver Maple Leaf. In the US Army it is a cluster of silver OAK leaves. In the British army it is a crown and a single 'pip'.
