Answer: Tactics to wear down the enemy through constant attack
Step-by-step explanation:
The statement "Tactics to wear down the enemy through constant attack" is not typically associated with the strengths of the Mongol Empire.
The Mongols were known for their use of psychological warfare and strategic retreats, which often involved feigning weakness or retreating to draw the enemy into a trap. They were not known for wearing down the enemy through constant attack; instead, they often relied on swift and decisive strikes to disorient and defeat their foes.
The other options - a nomadic lifestyle, the adoption of useful technologies from other cultures, and maintaining one of the largest armies in the world - are all well-documented strengths of the Mongol Empire.
