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).
For now, we'll just list 'em: iamb, trochee, spondee, anapest, dactyl, amphibrach, and pyrrhic. Those terms, of course, only cover the first half of what we call meter. The second half comes from the number of times that foot is repeated. If it's monometer, the foot is only used once. Dimeter repeats the foot twice.
