Wanna know Islam’s Greatest Military General?
While Islamic history is replete with extraordinary examples of military prowess and feats of arms, the majority of military historians tend to focus on the more familiar masters of the art of war. Historians usually count the likes of Napoleon Bonaparte, Julius Caesar, and even the feared Mongol steppe warrior, Genghis Khan, among the lofty ranks of the world’s Great Captains.
Clearly these are all highly accomplished men of war and rightly deserve their recognition as some of the most gifted battlefield commanders and strategists in history, there are yet others who deserve to be held in similarly high esteem.
Chief among these is Khalid bin al-Waleed, Islam’s first great general and a man so accomplished in war and personal combat that the Prophet Muhammad himself gave him the title of “The Sword of Allah”. he is top of all military commander in history
Khaled has excelled in each and every item of military strategy, his flanking action at Ohoud (before he became a Muslim) saved the day and altered the entire outcome of the battle. His brilliant campaigns against similar nomadic troops in the Ridda wars, and against a totally different Persian enemy in Iraq and modern Iran and later against Byzantium, showed great military versatility and ability to adjust.
His wars were always far from his homelands, requiring superb management of his supply lines, and his rush across the perilous wastelands separating the Levant from Iraq, to aid the Islamic armies besieged by Byzantian forces was daring and unprecedented, to march an army through waterless wastes and depend on animals as living water storage units
He (RA) should be placed at number one. If you read into the battles that he actually fought and won not only was he a great commander of the army but her was praised for his excellency in swordsmanship and horse riding skills. In his first ever time being the commander of the Muslim army he used his military experience to change a loss into a crushing victory.
He never lost in 100 battles + over 100 duels 1v1 come on man laugh out loud can you imagine dueling over 100 duels in front of 2 big armies everything depending on you he's one of only few leaders who actually fought with their soldiers such as alexander the great and risked their necks and still didn't get killed even though he was the first to run into the enemies and the last to leave :) he broke 9 swords in a battle once 9 swords

Wanna know why he’s an effective leader?
Khalid ibn al-Walid is the best military leader because of one quality that all others don't have: he never ransacked the territories he invaded, sparred the lives of women, children and old people.
