Hello, I'm BilCat. I noticed that you added or changed content in an article, Northrop Grumman RQ-4 Global Hawk, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page. Thank you. BilCat (talk) 09:15, 5 May 2020 (UTC)

Please do not add or change content, as you did at Sukhoi Su-30, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. BilCat (talk) 10:16, 10 June 2020 (UTC)
