El Impulso is the ability of the Volta Supremo. It sends out an EMP wave that knocks enemies over, disables security and stalls vehicles so you can hijack them, tanks included.
Fire it and an EMP wave spreads out around you. Enemies on foot fall over, alarms and security stop working, and vehicles shut down so their crews climb out. Then jump in and take the vehicle.
Finish the mission Libertad Rises, then buy the Volta from Juan with Depleted Uranium.
Yes for stealing tanks and shutting down an outpost alarm. Its range is short, so you need to get close to a helicopter to affect it.
Zeusito, the EMP Resolver weapon, reaches much further. El Impulso has a wider area around you, so it handles a group of vehicles better.
