FORT IRWIN, Calif. -- U.S. Army Cyber Command is deploying Expeditionary Cyber-Electromagnetic Activities Teams to support tactical commanders at National Training Center rotations, and the CEMA operations have tried to replicate real-world operations support through the cyberspace domain.CEMA is an Army initiative designed to provide tactical commanders with integrated cyberspace operations, Department of Defense Information Network operations, Electronic Attack, Electronic Protection, Electronic Warfare Support, Spectrum Management Operations, Intelligence, and Information Operations support/effects.According to Maj. Wayne Sanders, the ARCYBER CEMA Support to Corps and Below chief, success for the brigade combat team in the cyberspace domain begins at the D-180 planning conference -- 180 days before the unit's NTC rotation."The biggest thing for the D-180 are the key leader engagements," said Sanders. "[At those conferences] we can inform the brigade commander about what types of CEMA support we can provide to help him shape conditions for his battle to be able to close with and destroy the enemy."Sanders said while he doesn't foresee BCTs executing their own cyberspace operations organically, he does expect the commander and the staff to have an initial understanding of the CEMA environment and to provide their higher headquarters with a cyber effects request form. He said that if the brigade plans for an expeditionary CEMA capability to be brought out to support their operations correctly "then we can provide that for them.""If you're looking at this from a real-world perspective, if they identify that they are going somewhere in the world -- somewhere they would need additional capacity that they may not have coverage for -- they can submit that through a CERF, as a request for forces," said Sanders. "And the beauty of the Expeditionary CEMA Teams is their scalability and reach back."Sanders explained the ECT concept originated from the Chief of Staff of the Army, who directed the Cyber Support to Corps and Below Pilot in 2015. The pilot tasked ARCYBER to assess the best package of equipment, capability, authorities and personnel to support a BCT."That's why, out of the DOTMLPF-P (Doctrine, Organization, Training, Materiel, Leadership and Education, Personnel, Facilities and Policy) came the need for a force that provides the authorities, the senior and master level expeditionary cyber operators, and a quick turn cyber development capability, that doesn't exist right now in the Army," said Sanders. "It provides infrastructure support personnel that can provide the same thing as having people on the ground."Sgt. Maj. Jesse Potter, the operations sergeant major for the 780th Military Intelligence Brigade (Cyber), said that although this is the ninth rotation since 2015, it has been an iterative process to best replicate real-world operations, and more is being learned each time a rotation is conducted."We've learned that we were a very large logistical burden to the rotational training units. We learned our lessons about the CEMA capability that we can provide to a rotational training unit, and at the same time we were reducing the logistical requirement to provide that capability," said Potter."Eventually, we concluded that an expeditionary mindset, based on the commander's request for cyber effects, is best fitted with a plug and play capability," he continued. "Meaning, we need to identify the personnel that fit those requirements, ensure the teams are self-sufficient with a reach back capability to reduce the logistical footprint, in both a flyaway kit, light capability, to a more robust sustained operation, whether in a peer or near-peer environment, permissive or non-permissive environment."Potter also said another area ARCYBER is looking at was CEMA support at the division and corps levels. "What's missing, what's next, are the division and corps level exercises," he said. "Enabling the education of the commanders [is] through the institutional arm of the Army, which is primarily the mission of the Cyber Center of Excellence. That is what the CCoE is working toward --incorporating CEMA into all aspects of the PME (Professional Military Education).""And then for the higher level exercises, just like we've done for the NTC rotations, how does the staff enable cyber based effects that supports the commander's objectives, and what can they gain from having the cyberspace capability that they currently don't have?" Potter continued. "Because at the same time, that education will benefit the brigade combat teams."Furthermore, ARCYBER is not just looking at the development of the ECT structure and incorporating that support at the division and corps levels -- the command is also determining the organizational structure to command and control those ECTs."Regarding the ECT structure…you have individuals, put together as a team, predominantly from four separate organizations across three MACOMs (Major Commands) -- ARCYBER, Intelligence and Security Command, and the Cyber Center of Excellence," said Potter. "Moving to an organizational structure whereby the ECTs are part of a larger unit as the force structure solution means we no longer have an organization that's made up of a hodgepodge of people, further exasperating the issues that we have with the rotational training unit."Potter and Sanders said that's where they are now. Organic ECTs, all assigned to the same unit, and subordinate to ARCYBER will provide the Army with an expeditionary CEMA capability.ARCYBER used the lessons learned from the past nine NTC rotations to determine the optimized force structure they are proposing to the Army to stand up an organization with all those separate elements that were under different commands, to fall under one command with CEMA capabilities tailored to meet the tactical commander's objectives.
