The Australian and New Zealand Army Corps (ANZAC) was originally a First World War army corps of the Mediterranean Expeditionary Force. It was formed in Egypt in December 1914, and operated during the Gallipoli campaign.

Quietly the Germans brought in their best soldiers from the eastern front, selected elite storm troops, and trained them all winter in the new tactics. With stopwatch timing, the German artillery would lay down a sudden, fearsome barrage just ahead of its advancing infantry. Moving in small units, firing light machine guns, the stormtroopers would bypass enemy strongpoints, and head directly for critical bridges, command posts, supply dumps and, above all, artillery batteries. By cutting enemy communications they would paralyze response in the critical first half hour. By silencing the artillery they would break the enemy's firepower. Rigid schedules sent in two more waves of infantry to mop up the strong points that had been bypassed. The shock troops frightened and disoriented the first line of defenders, who would flee in panic. In one instance an easy-going Allied regiment broke and fled; reinforcements rushed in on bicycles. The panicky soldiers seized the bikes and beat an even faster retreat.

The Anzac myth refers to the exploits of brave young soldiers keen to prove themselves as representatives of a fledgling nation, albeit one with an ignominious convict past (Bennett 1988; Sayle 1988), who performed heroically for their ‘new’ nation which was formed only a generation earlier in 1901. In fact, many Anzacs fought as British Empire troops under the British flag at a time when many Australians referred to the United Kingdom as the ‘old country’ and still regarded themselves as British. Although many Anzacs undoubtedly fought bravely in extremely difficult conditions, their heroism has been embellished by journalists and war correspondents. Charles Bean, in particular, actively sought out stories of heroism on the battlefield and was instrumental in claiming that the Australian nation was ‘born’ at Gallipoli (Crotty 2009: 101). With the passing of almost 100 years since these youthful, citizen soldiers stormed what has come to be known in Australia as Anzac Cove, the Anzacs have come to be revered as national heroes and comprise a foundation element of the national narrative (Day 1998; Donoghue and Tranter 2013).

The storm battalions expanded into storm divisions by the winter of 1917-1918, in preparation for the upcoming Spring Offensive in March 1918.

These storm divisions were trained on the same Attack in Position Warfare
doctrine like the storm battalions, on a wider scale. The doctrine began with a brief
artillery barrage on targets, carefully sighted, and used high explosive and poison gas
shells. German storm battalions used unit tactics (Stosstrupptaktik) that allowed them
to first use skirmishers or scouts to ascertain potential avenues of approach or paths of
least resistance. The purpose was to get to the flanks or to the rear of any enemy strong
points. These approaches were exploited by the first wave of light machine gunners,
grenade throwers (bombers) and riflemen to protect their flanks.

General Erich Friedrich Wilhelm Ludendorff encouraged their deployment in every German division as they continued to evolve and very soon they had their own trench mortars, flame trooper, machine-gun, and grenadier detachments. German general Oskar Von Hutier would develop the Hutier infiltration tactics which the stormtroopers would maximize and use to deadly effect. By early 1917, more than 30 German divisions would have experimented, trained, and integrated the new assault battalions into their ranks.

Nine Tank Battalions were to take part (each of thirty six tanks plus six in reserve); D and G Bns were to be together in 1st Tank Brigade.

The Tank Corps units were re-equipped in time for the next major Allied offensive, the August 1918 Battle of Amiens. For the newly established Corps it was to be even bigger and, in the event, more decisive than Cambrai. Nine heavy battalions (324 tanks) were to lead the attack together with two light battalions (96 Whippets). 42 tanks were in mechanical reserve; a further 66 were to work with infantry and 22 were gun carriers, a total of 604 tanks. The two initial thrusts were to be South of the River Somme, 4 Tk Bde including the Fourth being on the left.

18.0 STOSSTRUPPEN
Stosstrupen were German infantry which
employed new infiltration tactics to break
the deadlock of trench warfare. In the
game, stosstrupen function like regular
infantry except as specified below.
18.1 How Stosstrupen Are Created
18.11 The Central Powers player may
begin using German infantry replacement
points to create stosstrupen units in July
1917.
18.12 To create a stosstrupen unit
requires seven infantry replacement
points. Stosstrupen may be replaced at
the normal cost.
18.13 No more than two stosstrupen units
may be created per game turn. There is
no fixed limit for replacing these units.
18.2 How Stosstrupen Affect Combat
18.21 The die roll is increased by one for
each supplied stosstrupen unit
participating in an attack.
18.22 Whenever stosstrupen participate
in an attack, the attacker must fulfill any
required loss by eliminating stosstrupen
units, before any other type of unit may
be eliminated.

The composition of storm units varied within these possibilities:
1 to 5 storm companies (infantry assault units}
1 to 2 machine gun companies (heavy machine guns)
I flamethrower section
I infantry gun battery (light mountain howitzers
or captured Russian guns)
I Minenwerfer company (trench mortars)

Besides the established storm battalions for each field army, ad hoc storm
units were often formed within infantry divisions and were usually led by a
cadre trained by the field army's organized storm battalion.

Established storm battalions assaulted with additional infantry from an
accompanying division. The second wave consisted of the elite
storm companies and the flamethrower section, with additional infantry support from the division. This second wave attempted to penetrate the enemy zones by pushing through weak areas to envelop enemy positions. Supporting these efforts was the third wave, about 150 meters behind, which contained the storm battalion's heavy weapons and similar additional support from the division.

This third wave provided fire to support the forward movement of the
storm companies and to protect the flanks of the penetrations. Behind· these
three waves followed the remainder of the accompanying division, which reduced pockets of resistance bypassed by the storm units, provided reinforcements, and maintained the momentum of the attack.

Accordingly, he reallocated the soldiers all across the Western Front to new divisions, designated by one of three grades: Mobile, Attack and Positional. The Mobile divisions, 44 in all, were staffed with the youngest and strongest soldiers, and they were trained and equipped to emulate storm troop tactics, particularly advancing in open order, acting independently, avoiding the enemy’s areas of greatest strength, infiltrating deeply, and thereby shattering the enemy’s carefully-built defenses.

Thirty more divisions fell in the Attack category, representing older but still capable soldiers; they too received this training, and were expected to serve as the reserve troops for the attack.

The German Army, however, could not train or equip every division for the
offensive. Lack of time, talent, and equipment created an unsatisfactory situation in which 56 divisions out of 192 were designated attack divisions,* ...

*The Germans used the terms Angriffsdiuisionen, Stossdiuisionen, or Mobilmachungsdiuisionen to describe attack divisions.
