2d Network Battalion operates, secures, and defends their area of responsibility of the Marine Corps Enterprise Network (MCEN) in general support of both the Fleet Marine Force (FMF) and Supporting Establishment (SE) by conducting Department of Defense Information Network (DoDIN) operations and Defensive Cyberspace Operations-Internal Defensive Measures (DCO-IDM); providing forces, communications control, and cybersecurity services in order to enable freedom of action across all warfighting domains and functions, while denying the same to adversaries.
The Department of Defense Definition:
The term "sexual assault" is defined as intentional sexual contact, characterized by use of force, threats, intimidation, abuse of authority, or when the victim does not or cannot consent. Sexual assault includes rape, forcible sodomy (oral or anal sex), and other unwanted sexual contact that is aggravated, abusive, or wrongful (to include unwanted and inappropriate sexual contact), or attempts to commit these acts.
"Consent" means words or overt actions indicating a freely given agreement to the sexual conduct at issue by a competent person. An expression of lack of consent through words or conduct means there is no consent. Lack of verbal or physical resistance or submission resulting from the accused's use of force, threat of force, or placing another person in fear does not constitute consent. A current or previous dating relationship by itself or the manner of dress of the person involved with the accused in the sexual conduct at issue shall not constitute consent.
