The modified triangle represents Fort McCoy's cantonment area configuration. The two pine trees allude to the Fort's location in western Wisconsin where the tree is a prominent feature. The white area suggests the abundant snow of the area's long winters. The green border suggests containment and support of annual Army training exercises.
