Place it right at your squad's entrance in a montage, then follow it with the enemy spotted sound for the callout and the bomb has been planted sound before cutting to the fight.
About this sound
A short three-second voice clip of a soldier firmly declaring 'We are Russians' in the middle of a combat moment. It feels bold, intimidating and oddly funny when dropped out of context, giving any group chat instant mock-serious squad energy. The line comes from the game Battlefield 3.
