In this age of advanced artillery, computers are taking the place of infantries to pull the triggers at the most perilous areas. The level of advancement is in such terms that now the marines or the armies don’t have to manually input the co-ordinates to launch any missiles, they only have to provide the voice command of the area they want to target and the computer automatically calculates the grid value and the next thing that needs to be done is to provide the password. Advanced triggers are loaded with laser sensors that allow the infantries to set traps and destroy heavy artillery vehicles of the enemies quite easily.
Laser sensors are also installed at the tip of the missiles which enables to guide the missiles into pin perfect aims. Many warfare guns are also developed with laser sensors. Theses sensors automatically pull the trigger when it senses certain movement at distances. Laser sensors have not only taken up the standard of the defence system of the countries to another level but also have added to the safety perspective to the millions of army, navy, marines etc. Thus laser sensors can be rightfully regarded as a life saver rather than life taker.
