Background
• This model is an adaptation of an earlier CNA model developed to
simulate endstrength changes during the 1990s force drawdown
• The model was uppdated for use in a pprojject examiningg various asppects
and future sustainability of a USMC force of 202K
– Predict future enlisted endstrength fixing accessions, or future accessions
fixing enlisted endstrength
– Scenario simulations (ex: change in continuation rates)
• In today’s session, I will demonstrate the model’s functionality and
present some results from scenario simulations
