Close-quarters combat

On January 6th, at the Capitol in Washington D.C., I've seen the most brutal hand-to-hand combat outside the movies

This military term seems to refer to fighting by hand, but it also refers to using striking weapons such as sticks, batons or knives, but certainly not guns.
Hand-to-hand fighting methods were largely employed in military training in trench wars and only started to decline after the second world war when rifles no longer had bayonet lugs
