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).
The second word in the phrase refers to how many metrical feet there are in each line. This is accomplished by attaching a prefix to the word 'meter,' like so: A meter with two feet is called ' dimeter .'. A meter with three feet is called ' trimeter .'.
