Hello, I'm Materialscientist. I noticed that you made a change to an article, Italian submarine Carlo Feccia di Cossato (S 519), but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Materialscientist (talk) 08:53, 17 October 2023 (UTC)

Please do not add or significantly change content without citing verifiable and reliable sources. Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Materialscientist (talk) 08:55, 17 October 2023 (UTC)

Please do not add unsourced or original content. Doing so violates Wikipedia's verifiability policy. If you continue to do so, you will be blocked from editing Wikipedia. Materialscientist (talk) 08:56, 17 October 2023 (UTC)

You may be blocked from editing without further warning the next time you add unsourced material to Wikipedia, as you did with this edit to Italian frigate Artigliere (F 582). Materialscientist (talk) 08:58, 17 October 2023 (UTC)
