A fiber optic cable has one end directly coupled to a semiconductor IR generating laser diode array and the other end is used to direct IR radiation at a soldier's wound for surgical purposes. The beam may also be used to illuminate a dark scene to detect the presence of a present threat such as a sniper. The components are conveniently carried by the medically trained person in his belt pack so as not to interfere with his freedom of movement. Disposable IR applicator tips may also be provided to be attached to the IR exit portion of the fiber optic cable.
