How do you command your squad in half life 2?

In Half-Life 2, you can command your squad, primarily consisting of the Resistance members, using context-sensitive commands. By pressing the "use" key (default "E"), you can instruct them to follow you, stay in place, or attack specific targets. Additionally, you can direct them to certain locations or interact with objects to help you progress through the game. The AI will respond to your commands, enhancing the cooperative gameplay experience.
