Large Scale Exercise 2021 Tests How Navy, Marines Could Fight a Future Global Battle - USNI News

The Navy and Marine Corps have bet big that they have locked into a workable vision on how they’ll fight in the future, kicking off a massive exercise last week to prove their concepts.

The two-week-long Large Scale Exercise 2021 will put the Navy’s Distributed Maritime Operations, the Marines’ Expeditionary Advanced Base Operations and Littoral Operations in a Contested Environment at a scale that spans 17 time zones, three global combatant commands and more than a dozen command staffs.

LSE was ordered by Chief of Naval Operations Adm. Mike Gilday to test if the shifts in how the Navy and Marines think they want to fight in the future work.

“We want to take a deeper look at DMO, LOCE, EABO and how they tie together. And so that’s important for us conceptually to ensure those concepts in a way we can visualize whether or not we need to course-correct, whether or not we’re headed precisely in the right direction,” CNO Adm. Mike Gilday said in December.
