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).
A specific type of foot is an iamb. A foot is an iamb if it consists of one unstressed syllable followed by a stressed syllable, so the word remark is an iamb. Pent means five, so a line of iambic pentameter consists of five iambs â five sets of unstressed syllables followed by stressed syllables.
