How to inform colleges about "confidential" work you have done

<p>Well for the past months i have been reasearching for and working with a military branch in my country on a project. The project includes the development of a technological device.</p>

<p>The information about the project is technically confidential, but im interested in informing the colleges im applying to about it because it is an important work/research i have done and it could help in my admission. How can I approach the colleges about it, i was thinking of submitting a PDF supplement with information regarding the research and development of the project but that is "illegal".</p>

<p>how would u guys do it?</p>
