1.1~nks in eo·opel~tion wi~h other In!antry weapons during the World lar.

The tank in tbe World War wae a new .eapon, both to tho.e actually uling it f ~nd to those with .boa it eOaoperated. The plans under which it was used .ere

largely exp.rimenta1. Thesl plans Tar1td in character from the highly spectaeulat"6.nd pra~tlcally inde pel1dent attack ot the entire Brit ish Tank Corpi at Cambra!,

)

to the assigning of Tlry .ma11 numbers ot them to n infantry unit, acting under the moet detailed order. al to obJectiYe" mie lon, route, and rate of advance.

:txperienc6 dlmonetrated that in order to overcome the antt-tank dehnse. of t he on ~y, .pe cial e.B detance -and co-operatlon fr 011 t be artill.ry and alr eervl ce. was absolutely '8s8ntl&l. Further Infantry and Tank Commandere soon learned that to obtein lueeln froll the use of their Tank., they JDust operate ln the doult coordination with the infantry they re .upporting. Tanks were developed, and exiet to pro,ide a meane whereby the infantry ie enabled to ae6Uml the otClnaiy.6.gain.t defensive ZODes organized in depth and using the power ot the machine gun to repel assaulte. Their d8Yelopment ~ook placi after maBsed artillery and poilon gae had failed to ma.ke such offensh. action of the infantry pose1ble. 'In worii"S o.ut the be.t methode tor the tank. to render thitt aeBittance to the intantry. it was found eeeiniial that the maximum ':'Of mutual under.tanding and .p1rit ot co­operation should Ixi.t ~etween the infantry and its tank ••

During the world War the Division had ftO separatl tank organization corres­ponding to the prs •• nt Divisional Ta Company. All tanke belonged to a 8eparat~

Corps and were Army Troops. for any action tanke were allott.d to the different Corps, and to Dlyisions as considered n'cIslary by Army Hladquarters. Onl of the governing principII. of this allotment was that tank. should be used in num­bers, or not at all. 101low1ng thi. principl. the llotment wal u.ually made at the rate of ODe Battalion of Tanks plr DiTleion. Thir proportion of tank. allow.d the Division Commander to dlmand from tbem a practically continuou. support for his general infantry assault from the ~ump·oft to the objectiYI.

Tanke were not TUlnerabl. to ...11 a~s tirl nor to Ihrapne1, and their greatest In'my was the i.Alated gunl and anti-tank ritle. Icatt.red through thl -nemr'. det.n8.e~ whicb could tire on them OTer open light •• Tanks could cro.e ord1n&rl trenche., and make lane. through enemy wire tor our InCantry, and deliver fire again.t the garrilon at deadly ranges. They could take a position but could not bold it, nar could they damage .enemy personnel that had taken reruge llndergro\lDd. Thee8 fact ••ere .~.ken into c-onsideratioft in wotking out the beet method. of Tank and Infantry co-operation, tbe glnlral principles of which .erl a.~tollow.: . , ."
