Final answer:
Army leaders are expected to influence beyond the chain of command by collaborating with other military branches, coordinating with international partners, and working with political leaders.
Step-by-step explanation:
Army leaders are expected to influence beyond the chain of command, meaning they have the ability and responsibility to exert their influence and make decisions that impact areas outside of their immediate command. This can include collaborating with other military branches, coordinating with international partners, and working with political leaders to achieve military objectives.
For example, during World War I, the general staffs of the great powers had significant influence in planning and tactics, which meant political leaders had to choose from a limited set of options provided to them by their generals.
Ultimately, the ability to influence beyond the chain of command allows army leaders to effectively carry out their duties and contribute to the success of larger military operations.
