TACTICS  

DEVELOPMENT UPON DEBARKATION :  Under cover of smoke from chemical mortars firing from landing craft, the section leader and riflemen move straight to the front in a rough V formation with about ten yards interval and about five yard distance between riflemen.  The light machine gun team and the mortar team deploy to the left in that order with similar intervals and distances. The wire cutting team, flame throwing team and demolitions team initially deploy to the right in a similar fashion while the two launcher subteams deploy within the "V" about twenty yards apart and about twenty yards behind the section leader.

STEPS IN THE ASSAULT :  
a.  The section leader.  Prior to beaching of the landing craft, naval and aerial bombardment have cratered the beach and full advantage of these shell and bomb craters is taken in the initial movements of the assault section.  The assault section leader looks for the principal enemy fortification in his zone of action and for supporting enemy emplacements.  He establishes communication with his supporting tank or gun by visual signal.  He locates the elements of his assault section and covered by the fire of the riflemen he moves forward locating possible points for breaching enemy obstacles, blind areas in the enemy fields of fire, etc.  

b.  The assistant Leader.  The assistant leader, a non-commissioned officer is the last man off the landing craft.  He assists the section leader; is prepared to take the section leader's place, if the latter becomes a casualty; keep informed of the general situation at all times; and is particularly charged with the responsibility of locating covering fires from open emplacements and bringing mortar fire to bear upon such enemy installations.

c.  The Light Machine Gun Team.  The light machine gun squad takes position well to the flank of the assault section, where it can fire upon enemy installations taking care  not to mask the fire of the supporting tank or gun.  Should its fire be marked by advancing riflemen, the gun is moved to a new position from which the original target can be engaged.  Short bursts of two or three rounds will be fired at the embrasure; however, the chief use of the machine gun will be in neutralizing fire from enemy open installations. 

d.  The Mortar Team.  The mortar team moves to a position where it can bring fire on possible targets with maximum protection; they will receive orders from the assistant section leader to bring fire on open emplacements, but may direct fire on such emplacements at his own initiative.  Fire is directed until the successful conclusion of the assault, when the mortar is prepared to fire on enemy concentrations and to break up enemy counterattacks.

e.  The Rocket Launcher Team.  The rocket launcher team moves up under the protecting fires of the riflemen, the machine gun and the accompanying tank until it reaches a position from which it can fire upon the embrasure.  Rocketeers should take positions so that they are no nearer one another than twenty yards and where if possible communication can be established with the section leader.  Fire is opened on the pillbox with armor piercing rockets to cover the advance of flamethrower and the demolitions party.  When the flamethrower signals "I am ready", by arm and hand signal, the rocket fire is lifted.  At the successful assault, the rocketeers advance to the next position or to attack a new pillbox as directed.

f.  The Flame Thrower Team.  The flame thrower team moves forward by short bounds, taking full advantage of cover, under the covering fires of the riflemen, the machine gun, the accompanying tank, and the rocket party until it reaches a point from which it can bring fire to bear upon the embrasure of the enemy pill-box.  The assistant flame thrower keeps close contact with the demolition party, and when that party is in position to begin its assault, he signals to the rocketeer, "I am ready", by arm and hand or other pre-arranged signal, whereupon the rocket fire is lifted.  The flame thrower party then opens with jets of one or two seconds and covers the placing of charges in the vulnerable points of the embrasure by the demolitions party.

g.  The Demolitions party.  Is "ball carrier" of the assault section for whom all the other teams do the "blocking". It works its way forward under the protective fires of the other weapons until it is ready to make the final movement to place the charges to destroy the pill-box.  At this time, the leader of the party signals to the flame thrower party, "I am ready". The flame thrower then opens fire, and under the protecting jet, the demolition party places the necessary charge or charges in the vulnerable portions of the embrasure.

The London doctrine conference had concluded that the assault upon the enemy coast had to be made by specially equipped and trained infantry sections as direct fire could not be depended upon to reduce pillboxes, and normal infantry weapons were powerless against concrete. Therefore beach defences were to be blown by hand placed charges by self-contained thirty-man "Assault Sections" that didn't exist in conventional infantry divisions.
