Ace Combat 6: Fires of Liberation (2007)

The following weapons appear in the video game Ace Combat 6: Fires of Liberation:

Assault Rifles

AK-type rifle

In the OP sequence, a shot of the Emmeria Press' frontpage shows pro-Generals soldiers in the Estovakian Army with an AK-type rifle. It's hard to make out the details.

Heckler & Koch G36

The Heckler & Koch G36 seems to be one of the main assault rifles used in the Estovakian Army.

Howa Type 89

In one cutscene, Emmerian resistance fighters can be seen armed with Howa Type 89 rifles when they stop Melissa and Ludmilla. One of the fighters aims his weapon at Ludmilla and is about to shoot her but is interrupted when a group of Estovakian A-10 Warthogs pass overhead, giving the women an opportunity to escape. The resistance fighter attempts to open fire on the fleeing women, but his weapon jams on him.

Machine Guns

Browning M2HB

In the aforementioned cutscene, the Emmerian resistance fighters can be seen traveling in pickup trucks ("technicals") with Browning M2HB heavy machine guns mounted in the beds. One of the fighters attempts to engage the attacking Estovakian A-10s with one, but is ultimately killed when the truck is destroyed. It should also be noted that when the M2HB is fired at the attacking planes, the spent casings are ejected in the wrong direction and the weapon fires at a much faster rate than the real M2HB would fire.
