Military forces the world over devote massive amounts of time and money to develop technology that will give their soldiers the edge. For example, US military contractors came up with the LS3 (Legged Squad Support System), a robot designed to transport the cargo of army squads operating in rough terrain and bad weather. The United States spent millions of dollars to develop the horselike concept before putting it out to pasture recently because it was too noisy.
But there is already a legged support system, one that has been in service for thousands of years: mules. The Turkish Armed Forces (TSK) still pays attention to these "organic cargo carrier systems" that provide support to commando units and teams operating in dangerous or difficult conditions. The TSK's 2016 budget has provisions to procure about 900 mules for the army.
