WASHINGTON — When President Donald Trump announced Monday that he was tapping  Lt. Gen. H.R. McMaster as his new national security adviser, many outside the defense world were left scrambling to discover what they could about a man one retired lieutenant general called the "21st-century Army's preeminent warrior-thinker."

Below, we've collected some of the best articles from our collection of McMaster-related stories, with the most recent presented first. In some, he's the featured interview; in others, he provides background and insights. Put together, they present a look at the worldview of a man who is suddenly in the national spotlight.
