​War is never a fun topic to talk about; however, it is important for us to have a brief overview of what will it be like. As technology evolves from time to time, weapons and fighting vehicles are also getting upgraded.  In the non-recent future, war zones  might be like this:
Or this:

So, 
What are some advances in weapons in recent years?

1. T-Ghost

​The Swedish T Ghost is a camouflaged tank that uses BAE's ADAPTIV camouflage to make it invisible to enemy thermal imaging systems. The Ghost tank also uses a high-calibre 120mm compact main cannon with new technology designed to reduce recoil and lower overall vehicle weight. 
The result is a nimble and powerful medium fighting tank. The bleeding edge technology on this tank, in theory, allows the users to strike first before the opposing forces even realise they're there. 

2. ​Magneto Hydrodynamic Explosive Munition (MAHEM)

The MAHEM weapons system by DARPA uses a magnetic flux generator to fire a projectile without the traditional use of chemical explosives creating a more efficient and precise launch system. This projectile weapons system also uses molten metal to penetrate enemy armoured vehicles increasing lethality and effectiveness on the battlefield. ​

3. ​Taser Shockwave

The TASER Shockwave is a large-scale area denial system designed to help assist with riot control situations. Essentially a large modular system for firing numerous TASER X26 stun guns in a 20-degree arc with a 25-foot range. Not something you'd want to be anywhere near when it went off.
The TASER Shockwave is also capable of being daisy chained with multiple other units increasing area coverage and presenting an even bigger threat to violent rioters. A shocking piece of riot control weaponry for sure.
