Itwas duringthisperiod, and especiallyafter the Normandylandings, thatmostUS divisions enteredcombat. Bythe endof 1943thedefeatoftheAxispowershadbecomealmostinevitable, eventhough the toughestfighting still layahead. In combat, the infantrydivisions proved, as before, to be the most useful and versatile fighting arm.

IThefirstvolumeisBattleOrders 17,USArmyInfantryDivisions1942-43. 4 • • Combat mission and preparation for war Thestoryofthewartimedevelopmentoftheinfantrydivisionsin the USArmy really began in March 1942, when Lieutenant General Leslie J. McNair took command ofthe newly created Army Ground Forces (AGF). The AGF owed its existence to the influence ofthe ArmyAir Corps (AAC), which had caused the WarDepartmenttoplaceallArmyunitsnotdeployedincombattheatersunder separate commands for ground (AGF), air (AAF), and service forces (ASF). The newcommandsassumedalltheresponsibilitiesofthe existingservicebranches fortraining, organization, anddoctrine. BygroupingallairunitsundertheAAF, the AACwouldbringitselfastep closerto becomingan independentservice. McNair hadbeen involvedin organizational matters since World War I. As a colonel, he hadbeenthe chiefofstaffofthe 2dInfantryDivisionwhen itfield tested the prototype triangular division in 1936-37. Based on the experience gained from these tests, in March 1938 McNair proposed that the War Department adopt a very austere division of 10,275 troops. Although the War Department largely accepted his recommendations it permitted a series of individually small but cumulatively large manpower increases, which byJune of 1941 raised the strength of an infantry division to 15,245. The organization tablesfortheApril I, 1942division(discussedindetailinBattleOrders17)added self-propelledartillery, moreandheaviertrucks, and 49 moreantitankguns, but only269 more men. McNair had taken overthe AGF onlya monthbefore this, toolateto affecttheWarDepartmentdecisionto adoptthe newtables. McNairwasoneofthefewseniorAmericanofficersin 1942whounderstood the need to economize on both manpower (despite the draft) and equipment (despiteindustrialmobilization).

Consequently it could send only 42 divisions to France beforetheArmistice, anditstillhadtostripsomeoftheseofmostoftheirmen in orderto fill out the others. For the newwar the War Departmentestimated that it would need at least 100 divisions by the end of 1943, despite the likelihood ofmuch largerdiversions ofmanpowerinto naval and air forces. Although the United States was to become the "Arsenal of Democracy" it needed time before the output of its industry could match the needs of the troops. TheUnitedStateswasalso exportinglargeamountsofequipmenttoits allies. Shortages of strategic materials, especially steel, rubber, and gasoline, placed further constraints on the equipment available. The biggest constraint ofall, however, wasthatnoUS divisionwouldbeofanyvaluetothewareffort unless it could be shipped overseas - but to do that required cargo ships, and 6 there were never enough of them.

Therefore, McNair reasoned that an infantry division had to use as few menand strategicmaterials as possible andminimize the numberofcubic feetitcouldfitinto.InthelightoftheseconsiderationsMcNairfoundtheApril 1942infantrydivision inexcusablyextravagant. McNair concluded that the only long-term solution was to rewrite the infantry division organization tables to make them as "lean" as possible. To do this, he established the AGF Reduction Board. The "no-men," as the Table I:Infantrydivision members of the board came to be called, reviewed and modified all ground officerrankabbreviations force tables oforganization to achieve reductions of 15 percent in personnel (1942-43) and 20 percent in motor vehicles, but without cutting combat effectiveness. Rank Abbr. McNair personally participated in the work of the board and became the Majorgeneral MG biggest "no-man" of all, often saying "no" to his own "no-men." The "no Brigadiergeneral BG men" slashedthe proportionoforderliesto officers, gave as manylighttruck drivers as possible additional duties such as working in the kitchens, and Colonel COL eliminated "luxury" items. Company headquarters lost their tents and were Lieutenantcolonel LTC allowed only one portable typewriter each. No chairs, safes, or tables were Major MAJ allowed in any headquarters belowdivision level. The "no-men" assigned all personnel and equipment to specific vehicles and permitted no "reserves." Captain CPT They also increased the use of trailers since these considerably extended Firstlieutenant ILT the payload of the available trucks. Though leaving all "offensive" weapons Second lieutenant 2LT in place, they slashed anything whose main function was to increase Warrantofficer WO self-sufficiencyin security or supply. 7 In particular, McNair tried to discourage what he called "empire building" or the tendency of every arm and service to augment itself as if it had to win the war alone. An example was the persistent demands by many division commanders for their own tank, tank destroyer, antiaircraft, reconnaissance, and militarypolicebattalions so theycouldhandle everycontingency, not just the ones most likely to occur. There was also the tendency, deeply rooted in American society, to encumber the military with comforts, conveniences, gadgets,technicians, "experts,"specialservices,andcomplexcommand-control systems. Naturally, once these additions got started, they multiplied exponentially. Forexample, ifonewantedtoincreasethenumberofdentistsin a division one would also have to increase the number of dental technicians. Dentists and technicians had to be fed and required more cooks. Cooks, dentists, and technicians needed. trucks and their drivers and mechanics. Cooks, dentists, technicians, drivers, and mechanics needed medical care and that meant doctors, nurses, and medical technicians. The cooks, dentists, technicians, drivers, mechanics, doctors, nurses, and so forth needed clothing andthatmeantmorequartermasters- andofcoursetheyallneededdentalcare, which again increasedthe requirementfor dentists. McNairwas determined to nip such expansionin thebud. The "no-men" uniformly observed certain principles. First, for local air defense they replaced all Browning Automatic Rifles (BARs) outside the rifle squads with smaller numbers of much more effective M2 .50-caliber machine guns. Second, theyreplacedabout40percentoftheantitankgunsinadivision with large numbers-of the new 2.36in. antitank rocket launcher Ml or "bazooka."Neitherthebazookasnormostofthe .50-calibermachinegunshad Infantrymen crossa blown-up assigned gunners.
