The 6 AA battery pack is probably due to a general movement within the U.S. Military procurement system to move away from #Lithium123|s. One reason for this is practicality because 123s cannot be found in many parts of the world. But the other is because China just so happens to have the largest reserves of Lithium in the world. If the United States ever went into an actual war with China, or if China completely cut off its Lithium supplies, spare batteries would be in short supply.
