The new technology is not only on mobile devices: remote-controlled missiles and unmanned aircraft (drones) cost millions, but as it appears with the new technologies being discovered, death will be much cheaper. Smart weapons with lasers are known for their accuracy but usually cost a fortune.
The magazine Economist reports that the most expensive technology at the moment is missile smart weapons technology. A single subsonic long-range Tomahawk missile costs about 1.5 million dollars, while the air-to-ground Hellfire missiles weigh only 50 kilograms, and cost 115,000 dollars each. 
Another air-to-ground missile, a member of the same family, called Javelin costs 147,000 dollars and can be used to kill individual soldiers hiding in “difficult” holes.
Surely $147,000 for a hidden soldier is far too much, but these specific weapons are used extensively for targeting hidden ISIS insurgents.
This observation has also been made by the American forces, and thus recently a series of smart weapons are being developed that use cheaper materials. The development of the new APKWS II (Advanced Precision Kill Weapons System) by BAE Systems is the perfect example. 
It is a clever version of a traditional 70‑millimeter rocket, but it can hit with an accuracy of one meter with the help of a laser that searches for and detects the target by adjusting the rocket's fins accordingly. The US military (and not only) can acquire this specific rocket for $28,000.
The United States Navy is said to have upgraded a similar 70mm missile and created the new low‑cost weapon system Low‑Cost Imaging Terminal Seeker (LCITS). This particular system was developed for the sea and tracks its targets using heat instead of employing any laser technology.
However, the top spot is held by the Forward Firing Miniature Munition (F2M2, or Spike missile), which was developed by the Naval Air Weapons Station company based in California. It uses a smart optical guidance system that can “lock” onto objects or laser points and is powerful enough to destroy small targets.
Steve Felix, the head of the Spike missile project, managed to create a weapon with cheap materials, weighing only 3 kilograms, the size of a handgun and costing only $5,000.
Thus, as you understand, each army will be able to enjoy much cheaper smart weapons as they will soon be able to exchange a missile that costs $1.5 million for many small smart weapons of $20,000 each.
Naturally, manufacturers and governments have a very good justification for the cheaper death, since cheaper weapons also mean more tax relief for each taxpayer.
