INSPECTION BY G.G.C.The G.G.0. makes sure that the Recoil, Laying, Fis~ingand

Ammunition arrangements of the gene are correct, by asking thenumbers,andby inspection,if necessary.

He thenorders3 to loadadrill cartridgefitted with are electricprimer or adapterarid electric tube,the Layer to pressthetriggerfirmly and2 to closethe breechby pushingtime leverfromhim withhis right handuntil thebreechscrewis locked, i.e., whenthelowerstudon time turning lever of the safety stop is halfway downthesafetybracketon theleverbreechmechanism. In this position timeprimer(or tube) should not fire, as the striker is held backfrommakingcontactwith thel)rimer (or tube) by time actionof time safetystop. Thefinal movementof the lever in fully closing time breechshould fire time primer (or tube). 2 opens thebreechanti extractsthe cartridge,using time extractorwith Ins left hand. Time firedelectrictubeis then extracted,or, if a primer hasbeenfired, anadapteris fitted.

The G.a.O.then orders 3 to reload and 2 to close thebreechamid open it again, taking carenot to work the (gnu) extractor.He orders3 to inserta percussiontube iii time adapter,and2 toclose time breechcarefully. He then orders 2 to cock thestriker,attachtime lanyard,andfire time tube. Time breechis then opened,thecartridgeaxtractsd.andtime chamberthoroughlycleaned.

After time inspection the 0.0. orders “Layer, 2 and a UnderCover,” andsits his detachmentat ease.NoTz.—All spare strikers should in addition he submitted to the

foregoing tests under the G.G.0.’s supervision, and time drillcartridgeplaced clear on oneside.

Time breechof an unloadedgun is left open unlessthe 0.0.0.orders it to be closed,e.g.,when loading will not take placeforsonicconsiderabletine.

The 0.0.0. then reports “A Group,Readyto Load,” or, if he haspreviously beenordered to load,he orders the guns to be loadedand reports “A Group, Readyfor Action.”

NoTz.—ire thick weatimer and after preparation for action for thenight, I/me 0.0.0. will always order his ,quns to be loadedandIe-i~~qunlookouts to ta/ce post.

ills report under thesecircumstanceswill be “A G’roup, Readyfei~.Action.”

G.G.C.’s Orders.The orders“Stand Fast,” 11 Action,” “ Under Uover,” “Firc, A. 1,”

or “A Group, UommenceFiring,” are never repeated,but are actedupon at once.

All other ordersmustbe repeated,or be followed by an executiveorder from the 0.0.

“A Group, Test Oircuit.” “A. 1, TestCircuit.”

2 openstime breech,if closed,short circuits the striker to somepart of time gun, and calls “ ~ time Layer pressesthe leverindicator,and, if there is a deflection,calls “ Correct”; ii there isno deflection, lie calls “iVo Circuit.”

If there is Ito time to overhaul time circuit, time G.G.C. orders“A. 1, C/mangeto Percussion.”Norz.—This test is only necessarywhenguns have been prepared

for action some considerable time before the order to loadisgiven. -

“A Grocep Load,” “A. 1 Load.”

NOTz,—T/1C0.0.0. does not give thl~eider until time neanbers arestanding steady in their places,or until the circuits have beenreportedcorrect.

Electric firing.—2 openstime breech if it has beenclosedby taking hold of the

leverbreech nmechanismnwith his right hand (palm to the right)andpulling it towards him as far as it will come, takiumg care imotto jar time carrieragainstthegun.

3 sle~sto his right without moving his feet, to receive acompleteroundfronm 4.NoT~.—Inreceiving time round 3 keepsthefront of time loading tray

slightly elevatedand the tray close to his body, thus minimisingthechanceof theprojectilebeing dropped.

5 picksup a completeround—shellin his left hanmi arid cartridgein his right (liaimds underneatim)—phmmceslid of cartridgeagainstbaseof shell andhandsthem to 4. He then stops clear to allow6 to move into position with ilme next completeround.

He thenagain swings to his left and receives timenextcompleteround from 0,7, or 5. .. -

N0TE.—Iffor anyreason3 is unableto loadhis round at once, 4 canrest /minmself byslightlybendingboth icneesand allowing shell andcartridgeto rest on his legsabovetheknees.

3 graspstime primer or adapter firmly betweenthe thumbandforefingerof his right handand forcestheround homeinto the gunwith a rapid and smooth motion. He then slews round antireceivesthenextcompleteroundfrom 4.

2 then closesthe breech witim his right hammd, placeshis riglmt.wrist on time chinonmeterplane,time extendedfimigers touching theLayer lightly on the shoulderamid calls “Ready.”

Percussion firing.—NoTE.—Atpercussionfiring thelead to thestriker shouldbedetached

as it mmmamj causea mnissfire.As abovewith thefollowing exceptions:—

After 3 hasenteredthecartridgewith adapter,but with no tube,2 closes time breech, to ascertainthat time charge is lmome, thenopens timebicecli carefully, so as not to work time gun extractor,andwlmen 3 haspat in the tube,closesit carefully to avoid jarring thetube. 2 thencocks thestriker, attachesthe lanyard,calls “ Reedy,”andstandsby to fire on the order“ Fire” from the Layer.

To Fire,Electric firing.—

“Gun Fire” is theonly method of fire, and on time G.0.C.’sorder“ CommenceFiring,” 2 closesthe breechandcalls “Ready,” and timeLayer, whenaccuratelylayed,fires.

Fire is continued as rapidly as possible.

Percussionfiring.—Similar to electricfiring, exceptthat 2 attachestime lanyard and

calls “ Ready,” and on time om-der “ Fire” from the Layer, 2 pullsthe lanyardamid fires the gun.

NIGHT FIRING.It is most important that Layers who arebeingtrained for niglmt

firing shall at all timesbe made to close their eyeson firing.

AFTER FIRING.As soon ims the gumm is fired 2 graspsthe levem’ breecim mechanism

A cartridge so left signifies mm Shell in the Bore,” and preventsdoubleshutting.

N0TL— Unloading time cartridge is merelya further safetyprecautionwhich nmaybe renderednecessaryat peacepractice.

MISSFIRES.Electric Firing1

If, when the Layer pulls the trigger, the gun fails to fire, liereleasesthe trigger and calls out “close theBreech.”

2 gives time L,B.M. a smart tapwith hisright hand,andascertainsby inspectionthat it is home; he then calls “Ready.” The Layertlmeri again pulls time trigger, and, if time gun again miasfires, lieholds the trigger pulled while ho counmts“One, Two, Three,Four”aloud in slow time ; if it still fails to fire, lie releasesthe triggerand calls “A. 1, J1issJire.”

The Layer contiminesto follow thetarget.TIme 0.0. themi orders“Stand Clear,” and all the numbersstand

clear.Time 0.0., 2, and.3 look round the circuit, keeping clearof recoil.They carry timis out asfollows

(i) If mmo deflection is givenby time pistol grip they look for abreakin the circuit, andseeif time fault caim be foumid andcorrected (such as lever breech mechanismnot home,contactsor bimmduimg screws loose). The fault if foumid isremediedandfire continued.

(ii) If a deflection is given by time pistol grip they hook for ashort circuit, and if found they remedy it and continuefiring.

No’rx.—If time fault is found and cannotbe quickly remediedac/mangeis at oncemadeto pem’cussionfiring.

If the fault cannot be found time detachnsemit, excepttime Layerand Setter,“ Ta/me (lover” by orderof theG.0.

NoTE.—” Take Cover” does not mean taking up “positions mendercover,” but mmmeames going to positionsof safetyshould the gunhappen to flue. (Ywiridgeswill also beput in a position ofsafety. A sentry should, in additlom, be detailed to prevemmtpersonsinterfering wit/i timegun.

In peace practice the Layer keeps the gun layed in a safedirection. (In war the safestdirection is that of the vesselbeingengaged.)

After a pauseof five minutesthe0.0. placeslmimsehf clearof andin front of the breech on the left side,and opensthe breechbyapplying the loading tray to time leverbreechmechanism.

After cefurtherpauseof one minute time 0.0., still keeping clearof the breech, removes time cartridgewith extractor and has itplacedon onesideclearof the gun.

No~~.—Duringany long pausein thefiring (or in peacepracticeattime conclusionof practice), theprimer is removedand examined.If it hasnotfired it is excimangedand set asidefor specialexami-nation; if it hasfired, the cordite will be destroyedandtime casewithprimer returned in time usualway. A cartridge fittedwithaim adapterand an electric tubeis treatedin thesameway.
