Marine Corps builds tactical cyber force to help with growing threats December 21, 2020 Only remote cyber operations were allowed in the past. The Marine Corps is changing that by pushing expertise to the fleet. (Master Sgt.

As a result, the Marine Corps is spreading expertise and resources from high-end cyber warriors to the fleet as it builds prowess in the domain, with new cyber-focused careers for Marines and first-time tactical cyber forces. The shift is a big one because presidential rules permitted only remote operations from Cyber Command for many years.
