If you were going to enlist in the military, which branch of the armed forces would you choose? And why?

The choice would have great consequences. The simple fact is that despite their similar charters, not all branches are created equal. Your choice will influence countless aspects of your life, including your post-military employment options and even the likelihood of whether or not you’ll survive your enlistment.

Gallup recently completed research into which branch of the armed forces most Americans would encourage someone to join. The Air Force came out on top.

Americans hold all branches of the U.S. military in high regard, but that does not necessarily translate into a desire to see their loved ones enlist. Fewer than half would be likely to recommend joining the Coast Guard (48%), Marines (43%) or Army (41%) to their children or grandchildren, while a majority would be likely to recommend the Navy (53%) or Air Force (64%).

As a chaplain, I heard some amazing reasons for people’s choice of service. One Army NCO told me, “I was leaning toward the Air Force until the Army recruiter pulled out this huge poster covered with every imaginable weapon, and said, ‘we’ll teach you how to use all of these.’” Not a bad technique for persuading testosterone-fueled eighteen-year-olds to sign on the dotted line.

One young woman who had served a tour in the Marines told me she didn’t even consider another option. “It was the Corps or nothing,” she said, before shouting “Semper Fi!” The USMC has the advantage of requiring fewer recruits and has brilliantly fostered a reputation as “the most prestigious of the military branches.”

A common motivator for Navy recruits seems to be the exotic locations of many of their installations. Can’t argue with that. Most of them are located on or near coasts, while the Air Force strategically places its bases where a falling aircraft would have the smallest chance of injuring someone on the ground. Places like Lubbock, Texas, where I served my first active duty tour at Reese AFB. [The people in Lubbock are amazing patriots.]

The Coast Guard, a sometimes-military organization, attracts people interested in their search and rescue ethos. This despite the fact that most of their mission involves enforcing laws and protecting the nation’s borders.

The Air Force draws lots of recruits who are interested in pursuing technical fields. The other services have similar career paths, of course, but the clear perception is that the Air Force offers the most. Still, it’s a bit embarrassing to share here the reason one friend of mine chose the USAF. Actually, it was his reason for choosing the chaplain assistant career field in particular. “I told them at basic training that I would take any job where I worked in a climate-controlled environment.” He was serious, but the last laugh was on him. When we deploy to the field, chaplain assistants are not only responsible their own safety, they have to protect their noncombatant chaplains as well (in any weather).

The different branches of the military go to war against their nation’s enemies—but they also maintain intense rivalries with their sister services. This competition is usually fun to observe . . . as long as alcohol is not in the vicinity.

C.S. Lewis’ Military Service

In the United Kingdom, the Navy is the senior service. Seems fitting for an island nation. That doesn’t mean that the Army traditions, which date back to historic militias, lack prestige.

During the First World War, C.S. Lewis was exempt from the draft. This, because he was from Northern Ireland. Despite this, he followed his brother Warren into the Royal Army.

Warnie was a career officer, graduating in 1914 from an expedited course at the Royal Military College, Sandhurst. Jack, in contrast, was one of many young college students who were subjected to a far more rapid training regimen, commissioned, and shipped off to the front.

In 1918 C.S. Lewis was severely wounded. One writer summarizes this event quite effectively.

The Lewis who crawled away from the carnage was not yet the C.S. Lewis of The Chronicles of Narnia, The Space Trilogy, The Screwtape Letters and Mere Christianity. Then, he was like so many others who fought in World War I—just another wounded soldier desperate not to bleed to death.

Eventually Lewis would wear another “military” uniform during the Second World War—that of the Home Guard (originally called the “Local Defence Volunteers”). But that is a curious story for another day. Lewis patrolled Oxford in a uniform similar to those portrayed in the photos on this page.

Lewis did not have formal personal ties to the Navy, although his maternal grandfather, a Church of Ireland priest, had served as chaplain in the Royal Navy.

During WWII Lewis developed a warm relationship with members of the Royal Air Force. He offered lectures at a number of installations and taught at the RAF Chaplain School. Although his first lecture began rather inauspiciously, his work with the airmen proved extremely fruitful.

Lewis is a fine example of the man of gentle demeanor who “does his duty” when called upon by his country. Had his lifetime not overarched two global conflicts, he would have been utterly content to remain a civilian and wear the “uniform” of an Oxbridge professor.
