France was one of the first countries to use aviation in combat: by the beginning of World War I it had 15 airships and almost 150 aircraft. Still, they were a part of the army until the French Air Force became independent on July 2nd, 1934. Today the French Air and Space Force employ over 40,000 people, and their main combat aircraft are the Mirage 2000 and Rafale.
From July 3rd (10:00 GMT) until July 6th (10:00 GMT), play 3 battles using French aircraft (rank III or higher, with an activity of not less than 70%) to receive the “French Air Force Day” decal.
Complete the task in random battles, except for Enduring Confrontation missions and [Assault] mode. Track your progress in the hangar by clicking Nickname → Achievements → Holidays → French Air Force Day.
You can find the decal in the “Holidays” tab in the Customisation menu.
