Hey buddy, thank you for letting us know this information. Amazingly, they have started producing flashlights with a recharger function. It may be helpful in some situations. Need to say that tactical flashlights are necessary for soldiers and sometimes can save the soldier's life. It is important to have your flashlight ready and not forget it before the operation starts. Glass breaker function is not that helpful because if you are with a weapon, it's easier to destroy glass using bullets or nade. If you are playing war games or going on long trips, buying
a good flashlight will be a good investment.
