US military history is filled with units whose names not only convey a whiff of battle – 101st Airborne, 1st Air Cavalry, 14th Field Artillery – but also describe what the unit did. But what is one to make of an outfit with such a vague name as 23d Headquarters Special Troops?

That unit consisted of 1,100 troops; and it was special, all right. The 23d, which served during World War II in England, France, Belgium, Luxembourg, and Germany, is the subject of “The Ghost Army.” Written and directed by Lexington resident Rick Beyer, the documentary airs Tuesday night on Channel 2.

After six years, beloved novelist Khaled Hosseini returns to the rugged landscape of his home country, Afghanistan, which he so evocatively brought to life in his two previous bestsellers, “The Kite Runner” and “A Thousand Splendid Suns.” In “And the Mountains Echoed,’’ however, Hosseini expands his scope out from a rural village to Kabul, Paris, San Francisco, and the Greek isle of Tinos.

In a series of interlocking storylines with shifting viewpoints, Hosseini delves into the joys, sorrows, and betrayals that alternately bind and fracture families. Once again, Hosseini’s lovingly rendered Afghanistan takes center stage, but in this book he extends his examination to encompass how the Afghan identity affects his characters’ decisions and lives in unfamiliar environments.

Globe TV critic Matthew Gilbert chatted with readers Friday on Boston.com. Here are excerpts.

Q. What about the new fall comedies? Anything you’re curious about?

A. I’m curious about “The Michael J. Fox Show.” Could be fun, if they don’t hammer the Parkinson’s jokes too much. He’s done that material on “Curb Your Enthusiasm” and on “The Good Wife.” And he should do some on his own show. But it can’t be the only focus of the series, or it will get old.
