In the past battlefields were specific, strategically chosen locations. With the exception of ambushes, wars of the past have a sense of locality about them. On the contrary, today’s armed forces no longer have that luxury. The battle can easily start in

In order to deal with such scenarios, the armed forces of countries all around the world are always on the highest alert, on the lookout for a missile launch or for troop movements. Furthermore, all these various possible scenarios require a lot of training for the soldiers before they can be sent to war. The training period lasts from at least a couple of months to several years, depending on a variety of factors. Additionally, an enormous financial budget is required for the training of all these soldiers, as well as for maintaining their alertness and battle readiness.

Today, we have drones that are piloted remotely and are capable of taking out targets. There is also heavy on-going research to make the drones more autonomous, thus reducing the requirement on humans. There are also legged robots in development that can aid and assist soldiers in moving their equipment and luggage from place to place, and is resilient to various land texture and features.
Although billions of dollars each year are spent on military robotics research, there are still few mass produced military robots being used in the real world. The following is a list of the most well known:
