It is clearly stated here:
Command-PE is available in several license versions to suit intended user base, feature needs and budgets:
Mil/Gov Edition is a “license upgrade” to commercial CMANO, and constitutes the ideal choice for government & private-sector organizations that do not require Command-PE’s additional features but wish to employ the commercial CMANO product for professional use. (Use of the commercial CMANO license in professional context is prohibited by the EULA)
Student Edition is suitable for use by military academies and other teaching/training environments where an affordable, mass-deployed software solution is desirable. It is very similar in feature set to the commercial version of CMANO but differs in licensing and pricing options.
Academic Edition is suitable for government & private-sector organizations that require Command-PE’s powerful analysis features, but do not need to alter the simulation’s default data & models.
Professional Edition offers the full power of Command-PE to users that need to alter any of the data or models of the Command simulation and integrate it it with their existing modelling, simulation and analysis solutions & workflow.
Per-seat, site-wide and enterprise-wide licensing options are available.
