Great! At last there is a manual for SWAT 2, Thank you very much TNGpt! These will help a lot! :)
All credit goes to Cy-Fox, the original uploader of those files here on GOG. Unfortunately, the topic was lost on the General Discussion area and easy to miss while the documents were also available on the multiissue patch in this Police Quest sub-forum, that people like me that did not have technical issues might not check.
And having it certainly helps enjoying this great game :)
