HIMARS Rapid Infiltration Exercise for offensive operations?

U.S. Marines with 2d Battalion, 10th Marine Regiment, 2d Marine Division, conduct a dry fire with the High Mobility Artillery Rocket System at Fort Bragg, North Carolina, Jan 5, 2023. This exercise is to increase the unit’s ability to transport and employ HIMARS in a multi-service offensive operation. 

Multi-Service Offensive Operations?

I keep forgetting that they're talking about maritime operations. So this is about the Stand In Force again.  Acting as the eyes and ears of the joint force even though the joint force will have aircraft and UAVs that can see out for hundreds of miles further than anything the Corps can put on the ground.
