How would you kill Hitler?

The mission

You have been tasked with the mission to kill Hitler. The mission is mandatory and you cannot decline it. You have access to a state of the art time machine: a simple Casio wristwatch in which you enter the time, date and location where you wanna travel to. It can travel to any point in past Earth's history, and it is programmed to automatically and safely return you to the present time as soon as the mission is completed.

You have access to all weapons available to humankind in the present day, but you can only take what you can carry.

You also have access to technology that will make you look ethnically German complete with Nazi uniforms, and a perfectly functioning universal translator.

How this thread will work

I will try to come up with a negative outcome for every answer in jackass genie style. Others are welcome to do the same!
