What is the British military laser pointer used for?

Early laser designators used a helium-Neon (HeNe) gas laser with a wavelength of 633 nm (nm). It is commonly used to produce laser beams with energies of 1 milliwatt or less. The cheapest laser Pointers use deep red laser diodes with wavelengths close to 670/650 nm. It's a bit expensive to use a 635-nm orange-red diode, but this wavelength is good for eye recognition. Laser Pointers come in other colors, but the most common is green light with a wavelength of 532 nm. In recent years, orange 593nm laser Pointers have also begun to appear. In September 2005, the 473nm blue laser pointer was introduced. In early 2010, a "blue" laser pointer (actually blue-purple) with a wavelength of 405nm emerged. So we came back to the question: "How far can I see my laser pointer recommendation?" As mentioned above, there are many factors to consider, but here are the basic guidelines. . A 200 mW green laser will show more than 10 miles, and a 1000 mW or more blue laser will show more than 10 miles. You'll need to factor in cloud cover, fog, and whether you're at a high altitude, but as a rule of thumb, you can expect a visible distance of 10 miles or more with a 200mW + green and 1000mW + blue laser.
