Performance
Despite un-reinforced concrete's poor performance as armour against heavy weapons, they would have been quite adequate to defend against the lightly armed German paratroops who were the anticipated enemy at airfields.
These were emphatically not "armoured cars", but merely a pillbox that could be moved from place to place. It was claimed to travel "at normal lorry speed" but in practice it was primarily allocated to the flatness of airfields. Most had difficulty moving at all owing to their excess weight, poor visibility and reduced radiator cooling. Some broke down completely and were either towed, or abandoned in place. Those built on steam wagon chassis coped well with the extra weight once boilers were removed, but were no longer powered.

Famous quotes containing the word performance:
“The way to go to the circus, however, is with someone who has seen perhaps one theatrical performance before in his life and that in the High School hall.... The scales of sophistication are struck from your eyes and you see in the circus a gathering of men and women who are able to do things as a matter of course which you couldn’t do if your life depended on it.”
—Robert Benchley (1889–1945)
“When a book, any sort of book, reaches a certain intensity of artistic performance it becomes literature. That intensity may be a matter of style, situation, character, emotional tone, or idea, or half a dozen other things. It may also be a perfection of control over the movement of a story similar to the control a great pitcher has over the ball.”
—Raymond Chandler (1888–1959)
“True balance requires assigning realistic performance expectations to each of our roles. True balance requires us to acknowledge that our performance in some areas is more important than in others. True balance demands that we determine what accomplishments give us honest satisfaction as well as what failures cause us intolerable grief.”
—Melinda M. Marshall (20th century)
