Following the events of September 11th, 2001 the US Military was sent to the Middle East. The Ohio National Guard also took part in these operations, sending individuals and small units to assist the larger military force there. In the fall of 2011 though, the Ohio National Guard sent the 37th infantry division (the 'Buckeye' Division) in support of Operation Enduring Freedom. This was the largest overseas mobilization since World War II for the Guard. The Ohio National Guard has also assisted in more domestic tragedies, having sent assistance during Hurricane Katrina, Hurricane Harvey, and Hurricane Irma. Assistance was also sent to Puerto Rico following the disaster caused by Hurricane Maria. In fall of 2019 legislation creating the Ohio Cyber Reserve was passed.
