In the video, the major appears to be upbraiding the soldier for not using a laser warning device to signal the approaching truck.
The beam itself will be produced by a device called a fibre laser.
It is in the process of shutting down its inkjet printer operations in order to concentrate on the faster growing laser printer and multi-function device markets.

The device consists of a camera, infrared laser to measure distance and a microchip that interprets the data to track people in 3D.
Since this device is already commonly employed to cool laser diodes, adapting it to control the new switches in bulk should be a cinch.
The more of these the laser sends in, the more light returns to the device and the higher the resolution of the resulting image.
The team hopes the laser could be built into a remote-controlled robotic device which could be despatched into a mine field, looking for vapour clouds.
The Light Touch can turn that image into a touch-screen that you can type on or swipe through with the help of a holographic laser projection and infrared sensor at the bottom of the device.

More modern versions of the tool add in a laser beam projector, which allows builders to level out the device and "draw" a long line of light across a wall, indicating an exactly level surface.
During their test drive, the team at Trusted Reviews found the device to work quite well -- mostly due to its 2, 000dpi laser sensor -- although they thought that the top-mounted buttons were somewhat difficult to access, and joystick mode can't be used to manipulate the Z-axis.
An alternative is Inertial confinement fusion (ICF), in which fusion of nuclei is initiated by heating and compressing a fuel target, typically in the form of a pellet containing deuterium and tritium contained in a device called a hohlraum (hollow space or cavity) using an extremely powerful laser.
His device will reportedly stream damp air containing microscopic water particles through a tube, while a laser diode beams light through the vessel onto a sensor located on the opposite side.
Originally an adaptation of an earlier device called a maser - an electronic oscillator that operated at very high radio frequencies - the laser was first demonstrated by Theodore Maiman in 1960.
When your iOS device is facing the wall, its camera monitors the field, using computer vision algorithms to detect your laser shots in real time, finally discovering a novel use for laser points that doesn't involve annoying rock bands or cats.
