First Nagorno-Karabakh War
On 12 June 1992, Azerbaijan launched an offensive and overran the northern area of Nagorno-Karabakh; they took control of Shaumian and Martakert regions. The Azerbaijanis used approximately 150 armored cars and tanks that they obtained from a division of the Soviet 4th Army deployed in Ganje. Consequently, thousands of refugees fled into the south and the Russian military, which was asked to intervene, sent helicopters and conducted bombardments from the air to stop the Azerbaijani offensive.
