As any serving or veteran soldier will tell you a good hot meal will warm you up as well as cheer you up in the most difficult of circumstances.
The 'Battle of The Bulge' was a prime example... Here a waiting-in-line GI leans forward to get a helping of hot beef stew and vegetables. The kneeling 'Chef' makes sure everyone gets a fair share of this hot chow before they once more return to their foxholes and dugouts in the frozen fields and forests of the Belgian Ardennes in December 1944.
Note also the big metal pot and the neat little field cooker. And if it may not be the finest 'cordon-bleu' cooking in the world... it sure as hell beats a handful of snow and a cold can of 'C' rations!
