Here's an interesting bit of cultural trivia that I'm betting most Americans don't know.
Here in America, it used to be that we referred to our fighting men as either "doughboys" or as "Johnny." The term "doughboy" was probably most popular during World War I, which ended in 1918, but seems to go back to the late 1840s (reference). The term "Johnny" seems to go back to America's Great Civil War, fought in the 1860s (reference).
For whatever reason, both "Johnny" and "Doughboy" fell out of favor by the middle of the 20th Century. The oldest term for America's fighting men, "Yankee," is not quite so widespread, at least among Americans, since while it goes to our earliest days as a country (reference), to American fighting men and women it brings up the unpleasant years of our Great Civil War of the 1860s, because the rebels called the (eventually winning) forces "yankees." The phrase "yankee go home" was offensive to 20th-century American troops not just because it was insulting, but because many American troops just didn't want to be called that. Good or bad, it is so. It reminds them of bad blood they just don't want to bring up again, even though it's nearly 150 years in the past.
(Which is why most of you Aussies and Brits ought to be a bit careful about calling us Americans "yanks" too casually. Even though most of us are well over it all by now, a few of us still aren't. Even though we mostly love you guys anyway.)
So the preferred term in America (and abroad) seems to have become "G.I. Joe," which has its origin in popular toy soldiers and comic books (reference). Today, you can go almost anywhere in the world and, no matter what language they speak, they probably know who "GI Joe" is. While you might mean to be either insulting or complimentary, most in America's armed forces will respond to it. Yes, not just members of our Army's General Infantry, but also the Marines, Air Force, even Navy or Coast Guard will not be offended to be called "GI Joe" if they're abroad. Mostly they know that good or bad, it represents them. Most of them even kind of like it, in my experience anyway--yes, even the female service members, who also don't tend to mind being called "GI Jane." So long as you're not sneering at them, anyway (and if you are sneering they might just kick your ass).
Assuming you agree with all of the above, here's an interesting cultural observation:
It was with a bit of a shock that a few years ago I realized that the Brits had their own term for their fighting men and women:
"Tommy." Or "Tommy Atkins."
I don't know if the Aussies or the Canadians still do this, but "Tommy" seems to be the preferred nickname of British fighting men around the world. Or at least it was up to 30 or 40 years ago, anyway. I don't know about today, but I've seen it a lot in my readings.
In 1969, The Who released one of my top 100 favorite albums: Tommy. Although thematically it is a little naive, and very much a product of its time, it deals with the idea of war and its horrors. I no longer agree with its main themes, but I do think it is musically beautiful. Yet it was only fairly recently that I realized that its title is intentionally ironic: "Tommy," at least at the time, was almost as emblematic in the British mind as representing her fighting men as "GI Joe" is to Americans today.
I'm not sure if "Tommy" is still so emblematic to the Brits today, but I know it was at one time. This was probably best-expressed in a classic Rudyard Kipling poem, which deals with how British soldiers were treated in the late 19th century--often cheered on, but more often forgotten when they were no longer convenient. I reprint it below for your pleasure.
Please note the reference to the red-coats here, you Americans. Also note that to this day the lower-class Brits tend to skip the "H" in their words, so 'eroes means heroes, 'e means he, be'ind means behind, 'alls means halls, and so on. They sometimes also like to skip their d's and f's, so an' means and o' means of and so on. Also, a publican is a pubmaster, i.e. a bartender:
I went into a public-'ouse to get a pint o'beer,
The publican 'e up an' sez, "We serve no red-coats here."
The girls be'ind the bar they laughed an' giggled fit to die,
I outs into the street again an' to myself sez I:
O it's Tommy this, an' Tommy that, an' "Tommy, go away";
But it's ``Thank you, Mister Atkins,'' when the band begins to play,
The band begins to play, my boys, the band begins to play,
O it's ``Thank you, Mr. Atkins,'' when the band begins to play.
I went into a theatre as sober as could be,
They gave a drunk civilian room, but 'adn't none for me;
They sent me to the gallery or round the music-'alls,
But when it comes to fightin', Lord! they'll shove me in the stalls!
For it's Tommy this, an' Tommy that, an' "Tommy, wait outside";
But it's "Special train for Atkins" when the trooper's on the tide,
The troopship's on the tide, my boys, the troopship's on the tide,
O it's "Special train for Atkins" when the trooper's on the tide.
Yes, makin' mock o' uniforms that guard you while you sleep
Is cheaper than them uniforms, an' they're starvation cheap;
An' hustlin' drunken soldiers when they're goin' large a bit
Is five times better business than paradin' in full kit.
Then it's Tommy this, an' Tommy that, an' "Tommy how's yer soul?"
But it's "Thin red line of 'eroes" when the drums begin to roll,
The drums begin to roll, my boys, the drums begin to roll,
O it's "Thin red line of 'eroes" when the drums begin to roll.
We aren't no thin red 'eroes, nor we aren't no blackguards too,
But single men in barracks, most remarkable like you;
An' if sometimes our conduct isn't all your fancy paints:
Why, single men in barricks don't grow into plaster saints;
While it's Tommy this, an' Tommy that, an' "Tommy, fall be'ind,"
But it's "Please to walk in front, sir," when there's trouble in the wind,
There's trouble in the wind, my boys, there's trouble in the wind,
O it's "Please to walk in front, sir," when there's trouble in the wind.
You talk o' better food for us, an' schools, an' fires an' all:
We'll wait for extry rations if you treat us rational.
Don't mess about the cook-room slops, but prove it to our face
The Widow's Uniform is not the soldier-man's disgrace.
For it's Tommy this, an' Tommy that, an' "Chuck him out, the brute!"
But it's "Saviour of 'is country," when the guns begin to shoot;
An' it's Tommy this, an' Tommy that, an' anything you please;
But Tommy ain't a bloomin' fool - you bet that Tommy sees!
I have to say, I don't know who "Mr. Atkins" is above, although I'm certain he was someone important. I'd love to know. He doesn't seem to have been a Prime Minister, but I'm not sure otherwise. I do note that there seems to be no Wikipedia entry about this, shamefully, although I'll happily work with anyone who wants to help me in creating one.
Every time I hear about British fighting men and women doing themselves proud, I do say out loud, "Go Tommy go!"
I wish more people would.
I mean, that whole nasty business in the 1770s is behind us now, yes?
(Do you Aussies or Canadians or anyone else have a similar afectionate name you use for your brave military men and women? I'd like to hear about it if so.)
