Q. How can I find CONOPS examples

You'll be able to find the different Joint Publications online in DTIC. I found this resource that explains the concept of operations with links to different publications, including some found in DTIC ,such as Joint Publication JP 5-0 : https://dap.dau.mil/acquipedia/Pages/ArticleDetails.aspx?aid=f8f70a76-5dda-4346-9bfb-7ef0608f71bb

Please let me know if you need any further research assistance.
