U.S. Marine Corps: Large-Scale Military Exercise “Steel Knight”

Exercise Steel Knight 25 was a large-scale, multi-domain military operation conducted by the I Marine Expeditionary Force (I MEF) in late 2025. Set across a vast training area spanning Southern California and Arizona, it served as the high-stakes final certification for units slated to deploy as the next rotation of Marine Rotational Force – Darwin in Australia. While previous Steel Knight exercises focused on conventional land warfare, this iteration functioned as a "campaign laboratory" for Force Design. It was specifically engineered to test the Marine Corps’ ability to act as a Stand-in Force—a low-signature, mobile, and lethal presence capable of persisting and fighting within an enemy’s weapon engagement zone. 00:00 Part 1 01:52 Part 2 03:36 Part 3 03:51 Part 4 04:49 Part 5 07:48 Part 6 08:28 Part 7 09:47 Part 8 13:16 Part 9 16:09 Part 10 17:36 Part 11 21:28 Part 12 23:01 Part 13 25:26 Part 14 30:14 Part 15 32:43 Part 16 35:35 Part 17 37:18 Part 18 43:05 Part 19 43:39 Part 20 45:40 Part 21 47:52 Part 22 51:19 Part 23 51:59 Part 24 55:24 Part 25 58:51 Part 26 01:00:22 Part 27 01:05:22 Part 28 01:07:33 Part 29 01:11:08 Part 30 01:14:29 Part 31 01:17:10 Part 32 01:20:18 Part 33 01:24:29 Part 34 01:29:41 Part 35 01:32:13 Part 36 01:35:02 Part 37 01:37:26 Part 38 01:43:15 Part 39 01:45:06 Part 40 01:49:07 Part 41 01:50:16 Part 42 01:50:51 Part 43 01:52:22 Part 44 01:54:08 Part 45 01:55:15 Part 46 01:57:05 Part 47 02:00:48 Part 48 02:05:02 Part 49 02:07:16 Part 50 02:09:43 Part 51 02:14:16 Part 52 02:18:57 Part 53 02:21:45 Part 54 02:24:30 Part 55 02:26:21 Part 56 02:28:12 Part 57 02:29:50 Part 58 02:30:12 Part 59 02:34:23 Part 60 02:39:19 Part 61 02:45:07 Part 62 02:49:17 Part 63 02:53:29 Part 64 02:54:59 Part 65 02:55:31 Part 66 02:58:21 Part 67 03:03:59 Part 68 03:09:14 Part 69 03:15:04 Part 70 03:16:00 Part 71 03:18:13 Part 72 03:23:50 Part 73 03:26:39 Part 74 03:30:47 Part 75 03:32:14 Part 76 03:35:07 Part 77 03:36:37 Part 78 03:38:12 part 79 03:38:35 part 80 03:42:51 Part 81 03:44:01 Part 82 03:45:48 Part 83 03:48:33 Part 84 03:50:45 Part 85 03:53:29 Part 86 03:54:38 Part 87 03:55:36 Part 88 Become a channel sponsor and you will get access to exclusive bonuses.
