The G11 is one of the most technically ambitious small arms ever developed, chambering a 4.73x33mm caseless ammunition round that eliminates the brass cartridge case entirely. Developed over 20 years by HK for the Bundeswehr under the Advanced Combat Rifle program, the G11 achieved extremely high burst-fire accuracy through its unique rotating-chamber mechanism but was cancelled when German reunification redirected defense funding.
