The Army has been upgrading and augmenting the attack system for its Abrams tank to ensure a clearer view for gunners looking to find, engage and destroy targets. The effort involves upgrading and modifying Kongsberg's Common Remotely Operated Weapons Station, a combat-tested technology that lets soldiers control and fire a vehicle weapon from beneath the protection of armor by virtue of looking at a video screen and leveraging advanced fire-control technology. Kongsberg took 300 systems and manufactured the smaller, lower profile systems the Army wanted to change as a way to help modify the weapons system for more efficient use.

Apart from its Russian engines, the J-20 is completely made and designed in China. And even then, future J-20s will be flying with a more powerful domestic engine, the WS-15, by 2021. In line with its increasingly sophisticated domestic arsenal, China's arms exports have become much more technically competitive in the last ten years; the 2015 U.S. Defense Department's Annual Report on the PLA even stated that China's ground systems in particular are globally competitive or nearly globally competitive. With selling points of low cost and affordable service, lack of geopolitical strings and upgrade packages, China has become the world's third largest arms exporter behind the US and Russia. With a series of recent contracting wins against Russian firms, it looks to expand its market share.
