All i know is that franco used north moroccans to fight They still notoriously famous for their brutality And after they kept being around as guards

Mohamed Meziane during the Spanish Civil War commanded a section of the Regulares Indígenas troops, who formed the shock troops of the Nationalist Army. Their fierceness in combat made them highly feared among Spanish Republican Army ranks. After holding many high military posts in Francoist Spain Mizzian reached the rank of Lieutenant General of the Spanish Army.

Trained at the Military Academy in Toledo, Spain, which he joined in 1913, he was patronized by King Alfonso XIII following his father's death. After graduating as a junior officer (alférez) Mizzian served for a long period in the Spanish army of the Spanish Protectorate of Morocco. He took part in 1921 in the Rif Wars against Abdelkrim. In 1923 he became a Captain and in 1925 a commander of the Spanish Colonial Army. During this time he established a deep friendship with Francisco Franco and once he even saved his life.

At the time of the coup of July 1936 Mizzian was posted as commander of the II Tábor of Regulares 5, based at Segangan, about 20 km from Melilla. He promptly took the side of the rebel faction and in his first battle of the Spanish Civil War, he stormed the seaplane base of Atalayón in Melilla where the commanders had refused to join the rebellion. Even though the loyalist troops defending the post surrendered, the base commanders, Commander Virgilio Leret Rui and Second Lieutenants, Armando Gonzalez Corral and Luis Calvo Calavia, were nevertheless executed the following morning along with all the men of the garrison, their place of burial remaining unknown.

After the Army of Africa commanded by Francisco Franco took over Toledo on 27 September 1936, Mizzian went with his troops to the military hospital and killed over 200 wounded Republican militia men in their beds, allegedly as a revenge for the Siege of the Alcazar. The proverbial cruelty and reckless behaviour of the Regulares troops were not random, but were part of a calculated plan of the Francoist military machine to allow these shock troops to spread fear among Republicans in order to demoralize them.

At the same time there was July 1936 military uprising in Melilla

The July 1936 military uprising in Melilla occurred at the start of the Spanish Civil War. The rebels seized the main garrisons of the Spanish Army in Africa and by 18 July had crushed the resistance of the army officers loyal to the Republican government. The supporters of the Second Spanish Republic were detained or shot.

One of the main goals of the Spanish coup of July 1936 was to secure Spanish Morocco, because the Spanish Army of Africa was the main shock force of the Spanish Republican Army. Their members were Spanish regular soldiers, the Spanish Legion, and Moroccan mercenaries, Regulares. Most of their officers supported the plot and rejected the liberal democracy. Only a handful of officers, such as General Manuel Romerales, the commander-in-chief of the Spanish Army in Morocco, General Gomez Morato, and the high commissioner, Placido Alvarez Buylla, were loyal to the Republic, and the Spanish workers in Morocco had no weapons and were isolated from the Moroccan population.
