It is difficult to say with certainty what would have happened had the armored tank not been developed, as it is impossible to know how events would have unfolded in a different scenario. However, it is likely that the development and use of armored tanks has had a significant impact on the course of military history, and their absence could have had a number of consequences.
One possibility is that the use of other types of military vehicles, such as cavalry or horse-drawn artillery, may have persisted for longer. The use of these types of vehicles was prevalent in the early 20th century, but the development of armored tanks eventually made them obsolete for many purposes. Without armored tanks, it is possible that these older forms of military transportation would have continued to be used in warfare.
Another possibility is that the tactics and strategies used in warfare would have been different in the absence of armored tanks. Tanks are a key component of modern military tactics and are often used to provide mobility and firepower to troops on the ground. Without them, it is likely that armies would have had to rely on other methods of achieving these goals, such as infantry or artillery.
Overall, the absence of armored tanks could have had significant consequences for the course of military history, but it is impossible to know for certain how events would have unfolded in this scenario.
