This invention pertains to a jam head and to a protection system. The jam head is rotatable around at least two separate axes and includes a first part rotatable around a first axis and a second part rotatably connected to the first part and rotatable around a second axis; a viewing port in the first part for viewing an object; at least one reflecting surface for conveying an image through the port; a camera optically connected via the at least one reflecting surface to the port; and a unitary infrared transmitting glass fiber of constant core diameter passing from the laser to and through the first and the second parts for conveying an energetic infrared optical signal and an exit port through which the optical signal passes. The protection system is mounted on a movable platform and includes a detector for locating a threat; an electronic and control system connected to the detector for receiving a signal from the detector; a laser connected to the electronic and control system; and the jam head.
