A caption should not be a literal description of the picture - that is the function of an alt tag. Patriot missile ie initial cap.
Be aware that official sources often get this wrong. Occasionally captions in picture galleries might be longer. Otherwise, lower case.
Pin ie initial cap only, no hyphen. And there is a distinction between percentages and percentage points.
Avoid going to three on mobile. This term is acceptable, although tautological since "Pin" stands for "personal identification ". Updated: 9 November paparazzi is a plural.
Pearl Harbor is spelt the American way ie without a "u".
