Synopsis. John Tyler was born on March 29, 1790, in Charles City County, Virginia. Like his father, Tyler served as governor of Virginia. Representing the Whig Party, he was the first vice president to become president due the death of his predecessor (President William Henry Harrison).
In the British Army, a rifle platoon from an infantry company consists of three sections of eight men, plus a signaller (radio operator), a platoon sergeant (a Sergeant), the platoon commander (either a second lieutenant or lieutenant) and a mortar man operating a light mortar (full strength of 27 men and one officer).
They are different echelons in a unit. For instance in my old unit there were 4 platoons in my company, 6 companies in my battalion and I didn't belong to a regiment but it would be the next step in line (X amount of battalion's in a regiment). Hope this helps.
