How do i export a soldier model from blender 2.79 to ue4? Please help

Hello. I am an indie game developer using blender 2.79 and ue4 for a project/game im working on. I have a soldier asset completed and rigged. How do I export the model to ue4? Do I need any external programs or addons and if not, what is the process to exporting character models into ue4? I would love and value a reply as soon as possible as I am in a tight work schedule. Thank you very much
