Troops tend to be deployed in 'battalions' (commanded by a lieutenant colonel) as a more convenient size of military unit and, as such, colonels have tended to have a higher profile in specialist and command roles than as actual commanders of regiments.
An iamb /ËaÉªÃ¦m/ or iambus is a metrical foot used in various types of poetry. Originally the term referred to one of the feet of the quantitative meter of classical Greek prosody: a short syllable followed by a long syllable (as in delay).
In the metric system, you measure length in centimeters and go to next higher unit by multiplying centimeters with 10. Thus, it is very easy to convert from a unit into another unit of length. On the other hand, in the standard system in Britain, a foot is the basic unit of length containing 12 inches.
