PACOM wants the services to operate across domains. The Navy already operates aircraft over land, but he also wants the Army, Air Force, and Marine Corp to help control the sea areas. We noted earlier, that it appears the Army may be moving to form something like the old Coast Artillery.
Now the US Naval Institute reports the Army is set to sink a ship during the 2018 RIMPAC exercise, presumably from land. In addition,
“Headquarters Marine Corps and [Marine Corps Forces Pacific] are working to deploy HIMARS (M142 High Mobility Artillery Rocket System) rapidly aboard ships to shoot at other ships.”
Now the Marines will probably do this from a Navy amphibious assault ship, but wouldn’t it be cool if the Army did this from a Coast Guard Cutter. That would really demonstrate cross service cooperation.
It is also something we might want to do operationally from an Icebreaker in the Arctic some day.
