artillery to fire armor-piercing rounds at enemy firing points and troops; there were no cartridges for the submachine guns; many of the men's uniforms and footwear were worn out; and it was impossible to commit the replacements into the fighting because of the lack of weapons. United States Army In the U.S. Army, there are four basic types of TOEs: The Base Table of Organization and Equipment (BTOE) An organizational design document based on current doctrine and available equipment. It shows the basics of a unit's structure and their wartime requirements (both for personnel and equipment). The Objective Table of Organization and Equipment (OTOE) An updated form of the BTOE, usually formed within the last year. It is a fully modern document and is up to date with current policies and initiatives. A Modified Table of Organization and Equipment (MTOE) A document that modifies a BTOE in regard to a specific unit. Used when a unit's needs are substantially different from the BTOE. A Table of Distribution and Allowances (TDA) A type of temporary TOE that is applicable to a specific mission. Used in an instance when there is no applicable TOE. Each TOE has a unique number that identifies it. When changes are needed, a table is not modified, instead, a new table is drafted from scratch. An example of an overall T/O change can be seen when the "Pentomic" organization was superseded by the Reorganization Objective Army Division (ROAD). During the 1950s, the Pentomic reorganization shifted the basic tactical unit from the regiment to the five-company battle group. Instead of brigades, an armored division had three Combat Commands designated: CCA, CCB, and CCC. On 16 December 1960, the Army Chief of Staff directed a reappraisal of division organization. Resulting studies were carried out between January and April 1961, and fully implemented by 1965. The resulting Reorganization of Army Divisions (ROAD) changed all division types (Mechanized, Airborne, Armor, Infantry and Cavalry) to an identical structure of three brigades of three (sometimes four) battalions. The ROAD division consisted of a mix of nine to twelve armor and infantry battalions based on its Mission, the likely Enemy, the Terrain/weather, and other forces available or Troops (METT). Each brigade would be assigned or attached the mix of battalions and companies based on the division commanders estimate based on METT. As operations continued, the division commander could task organize subordinate units as needed
