Having more men in a confrontation gives a numerical advantage to the larger group, they can surround and pressure the lone opponent, which makes it difficult for them to defend and counter-attack. Additionally, a larger group can also split into teams to perform specific tasks, such as surrounding the opponent, distracting them, or attacking from different angles. Another advantage is that the larger group has more resources to spend and more men to replace the injured or killed, making the fight longer and more exhausting for the lone opponent.
I can only laugh at the admirals because my post just keeps getting more and more solidified. LMAO
