ELI5: Do commanders actually give speeches before a battle (like in LOTR) and can people in the back even hear whats going on?

Modern warfare does utilize motivational speeches to generate morale among the troops. The content of these speeches are likely to include nationalist sentiments, self-professed martial superiority, focus on broadly shared values(ex:importance of protecting family.)

Antequated warfare did as well. Alexander Suvorov is a prime example that comes to mind. He used to carefully plan out battles ahead of time by accounting  for geographical features, possible reinforcements, etc. and then claim it was the work of god that led them to victory. On a  sidenote, he is one of the few undefeated generals in history.
