What is the final action after throwing a grenade?

After throwing a grenade, taking cover is considered the final action to ensure your safety as well as that of your team. This is crucial because grenades create a significant blast radius and can cause shrapnel to spread out, posing a risk of injury to anyone in proximity. By taking cover, you minimize the risk to yourself from the explosion and prepare for any subsequent actions, whether that be engaging the enemy or assisting your team.

Evaluating the impact, while important, would typically happen after ensuring that you are out of harm's way. Reloading a weapon does not apply in this situation since a grenade is not a conventional firearm. Signaling the team could be necessary in some contexts but ensuring personal safety with cover takes precedence immediately after throwing.
