With the proliferation of ballistic and cruise missiles by North Korea and China it only makes sense for the U.S. Army to respond by deploying systems in response. What is interesting about this is that the Army is using U.S. Navy missiles on their own land-based systems:

 The United States will deploy ground-based launchers capable of firing SM-6 and Tomahawk missiles in the Indo-Pacific region soon to address rising security threats, the Army Pacific commander has said. 

During his visit to South Korea, Gen. Charles Flynn said the U.S. Army has developed “long-range precision fires,” listing the SM-6 interceptor and the maritime-strike Tomahawk as missiles that could be launched from the new launch system.

It marks his first confirmation of the types of weapons systems to be fielded in the region this year. 

“That system will be deploying into the region soon. Where and when it’s going to go, I’m not going to talk about that now,” Flynn said during the interview with Yonhap News Agency at Camp Humphreys in Pyeongtaek, 60 kilometers south of Seoul, on Saturday.
