The 4th Infantry Division is a division of the United States Army based at Fort Carson, Colorado. It is composed of a division headquarters battalion, three brigade combat teams (two Stryker and one armor), a combat aviation brigade, a division sustainment brigade, and a division artillery.
The 4th Infantry Division's official nickname, "Ivy", is a play on words of the Roman numeral IV or 4. Ivy leaves symbolize tenacity and fidelity which is the basis of the division's motto: "Steadfast and Loyal". The second nickname, "Iron Horse", has been adopted to underscore the speed and power of the division and its soldiers.
