Einsatzgruppen GasVans GasChambers
Einsatzgruppen was the first way that Hitler used to kill off his enemy he thought that Jews were the big threat. Throughout the holocaust the gas chambers and gas vans were a big cause in the killings of all the jews. These became the fastest way for Hitler to kill the Jews. Hitler found this process much easier and much faster. The german soldiers didn't want the jews to have an idea of what was going on they told the jews that they were going to take a shower. When they were being brought to the gas chambers. Hitler finally realized what he could do to the population of the Jews (enemies), he took advantage.
Hitlers Extent to Kill
In its initial stages, the gassing was performed by mobile killing units, which operated sealed trucks with engine exhaust channeled into the interior compartments. The Einsatzgruppen didn't do enough, he needed his process to go by faster.

This video shows how Hitler's process went about. First he started with The Einsatzgruppen and that was working but not fast enough and it explained how his men couldn't handle killing people 24/7 throughout the day. Hitler began to create Vans to suffocate the Jews and the Gas Chambers to do the same it was a fast and easy way to kill.
More Deadly Process
The chambers still employed engine exhaust as the killing gas, at first. Due to the frequent mechanical breakdowns of engines, however in 1943 Commandant Rudolf Hess of the Auschwitz-Birkenau death camp ordered the replacement of carbon monoxide gas with hydrogen cyanide crystals which turn into lethal gas immediately upon contact with oxygen.
