The question is too broad to answer. Large scale military operations are inescapable in their scope and are reported in the general press. However, so-called "black ops" missions, conducted against specific targets are rarely if ever reported on, and in some cases are classified as national secrets.
The timeframe for releasing military operations to the public can vary widely depending on the specific operation and its classification level. Some military operations may be released to the public shortly after their completion, while others might take years or even decades before they are declassified and made available. It ultimately depends on the sensitivity and relevance of the operation to national security considerations.
