Army - Infantry Tank Top

The US Army currently employs six types of infantry: light infantry (consisting of four sub-types), "Stryker infantry", and mechanized infantry. The infantrymen themselves are essentially trained, organized, armed, and equipped the same, save for some having airborne, air assault, and/or Ranger qualification(s), the primary difference being in the organic vehicles (or lack thereof) assigned to the infantry unit, or the notional delivery method (i.e., parachute drop or heliborne) employed to place the infantryman on the battlefield. All modern US Army rifle platoons contain three nine-man rifle squads, with each type of infantry having a discrete TO&E.
