During the Emmeria-Estovakia War, Oleg Battalion were deployed to the city of San Loma. On February 15, 2016, the Emmerian forces launched the San Loma takeover operation as they needed the city's airfield to act as a beachhead for launching a surprise attack on the Estovakian Aerial Fleet.
Oleg Battalion with the help of several Estovakian helicopter units, would engage Warlock Separate Battalion as they attempted to push through to the city. However, due to the air support from Windhover Squadron and Garuda Team, Oleg Battalion along with their helicopter escort were completely wiped out, as a result Warlock Separate Battalion was able to push through to the city.
