The U.S. Army Ranger Handbook, updated last year, provides an introduction to this branch of Army special operations forces, with a mixture of history, lore, doctrine, operational guidance and survival tips.
“Tell the truth about what you see and what you do,” advised a historic Ranger document from 1759, reprinted in the current Handbook. “There is an army depending on us for correct information. You can lie all you please when you tell other folks about the Rangers, but don’t never lie to a Ranger or officer.”
