You do not need a GDEV account in order to obtain the Cameo model libraries; however, with a GDEV account you will have access to not only the models, but the AGVRA Wiki that provides a wealth of information, , including AGVRA user guidance. You are also invited to collaborate.  The requirements for obtaining an account are:

• You must be a DoD civil servant or under contract with a DoD entity
