Shilone SL-17

The Dragoons prefer bold color schemes that emphasize their presence on the battlefield. Unit aerospace fighters are commonly painted bright “canary” yellow or fiery orange, though the classic red-on-black scheme is still prevalent. BattleMechs are typically painted solid colors; red, gold or black are favored hues.
Alpha Regiment paints its units solid rust-red trimmed in black.
