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:
“Still be kind,
And eke out our performance with your mind.”
—William Shakespeare (1564–1616)
“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)
“They say all lovers swear more performance than they are able, and yet reserve an ability that they never perform; vowing more than the perfection of ten, and discharging less than the tenth part of one.”
—William Shakespeare (1564–1616)
