What the Army learned from a February cyber exercise
By: Mark Pomerleau  
The Department of Defense’s cyber warriors have started using the first cyber training platform developed by the military specifically for their needs.
The Persistent Cyber Training Environment will allow the operational cyber force to conduct large scale training as well as to rehearse for specific missions. Such a capability for cyber forces does not currently exist.
In February, members of the PCTE program office, which the Army is executing on behalf of the joint force, took the first working prototype to a joint cyber exercise called Cyber Anvil. Now, with what the Army is calling prototype B, cyber mission force teams from five different time zones, seven geographic locations with over 100 participants from across the joint force can simultaneously plug in.
