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).
I think the US scales down a level so they have a Captain running a company etc (they have more soldiers to command I guess)! The Company is commanded by a Major and in his company he has 3 Rifle Platoons of around 24 - 30 men each, commanded by a Lietuenant. The US still has 1st and 2nd Lieutenants, Australia did away with this years ago and only has 1st Lieutenants now.
