No, The Marine Corps will object to a substantial or significant use of any USMC insignia, including any use that implies any official or unofficial connection between the Marine Corps and you/your company, especially within your logo or branding strategy. For example, the USMC would object to a company logo that is based around or otherwise incorporates the Eagle, Globe and Anchor (EGA) emblem, and would request that such a logo be modified to remove the EGA. The bottom line is that USMC insignia should not be the centerpiece of your branding efforts because it will create the impression that you/your company are affiliated with or endorsed by the USMC.
Specifically, Section 765.14 of Part 32 of the Code of Federal Regulations (cite as 32 CFR 765.14) notes that "[r]equests from civilian enterprises to use or imitate the Marine Corps emblems, names, or initials will ordinarily be approved where use or imitation merely provides a Marine Corps accent or flavor to otherwise fungible goods. Disapproval, however, usually may be expected where such use or imitation reasonably would imply any official or unofficial connection between the Marine Corps and the user; tend to create the impression that the Marine Corps or the United States is in any responsible for any financial or legal obligation of the user; give the impression that the Marine Corps selectively benefits the particular manufacturer, commercial entity, or other user, as in displaying the Marine Corps emblem, names, or initials on musical instruments, weapons, or the line, and in using the emblem, names, or initials in connection with advertising, naming or describing products and services such as insurance, real estate, or financial services; or tend to subject the Marine Corps to discredit or would be inimical to the health, safety, welfare, or morale of the members of the Corps."
