This is an epic propaganda video for the US military during what sounds like a time they faced the Germans and Japanese in war. It is a testament to how valuable martial arts was and is today. This was effectively mixed martial arts training at its simplest form. The US soldiers and Marines were already trained in one generic defense style and were integrating others to complement it. It’s worth a watch and definitely a share for some street cred.
