Coast guard.....

So, suppose the Coast Guard was short about 10,000 personnel and “borrowed” them from, say, the Marines...

Just thinking out loud...

i just got into a pi$$ing match with GROK.
It finally came up with this:

"Broader Federal Lands as Needed for Mission Completion: This interpretive phrasing draws from the USCG's Title 14 authorities (e.g., § 522's "use all necessary force" clause) and PCA(Posse Comitatus Act) exemption, which allow flexible operations on federal lands in support of missions like border security or maritime enforcement. Legal analyses note that the USCG's hybrid military-civilian status enables "land-based operations on federal lands" without PCA constraints, extending to mission-essential activities (e.g., staging or pursuits in riverine border areas like Operation River Wall). For instance, in maritime-adjacent federal properties (e.g., wildlife refuges or riverbanks), the USCG can access and operate as required under DHS directives, without the same oversight hurdles as DOD force"

Which really doesn't clarify your "suppose"
