While ending “Civil War”, Sound designer Glenn Freemantle and monitoring sound Editor Ben Barker was informed by the director Alex Garland to his next film – “Warfare” -Baled on a real assignment in Iraq it would be even smaller and not contain any music. They were all in. But a little realized Freemantle and Barker what subjective and engrossing sound experience they were in.
Passion Project of Iraq know Ray Mendozawho served as military advisers for “civil war”, “Warfare“Tells about the enemy surveillance assignment that Mendoza was on as a young naval sealing communications manager who was transformed into an al Qaeda back hold in Ramadi, Iraq, 2006. Writing and directing with Garland, Mendoza took a unique forensic attitude to the terminated 24-hour order, and for the case, and for the end of all
“We just knew it was an absolute, brilliant opportunity for us,” Freemantle told IndieWire. “Everything would be realistic and real -time. We were really looking forward to going down to the set. It was a fantastic atmosphere. It was completely military situation all day, every day, even during breaks. So you knew how it would be.”
Filmed north of London in a studio set of recreation of the apartment building where Plato was placed, “Warfare” was chronologically managed with the camera running in blocks of 12-minute takes. Plato was surprised by Al Qaeda operatives next to it. The soldiers were first hit by a grenade thrown through a snicker hole in the wall, and then exploded one IED outside the building, injured serious medicine and sniker Elliott Miller (Cosmo Jarvis), to which the film is dedicated and leading little officer Joe Hildebrand, changed its name to Sam (Joseph). From there, the pelotone must stick to reinforcements to help them evacuate from the building.

Freemantle and Barker had many conversations with Mendoza about the sound of the shooting weapon “Everything was real and the knowledge we gained from Ray was incredible about how their perception of sound was, their perception of the bullets,” Barker told IndieWire.
“Like the snap you hear was very important,” added freemantle. “Because they hear the snap before hearing bang. Ray was very specific about the sound of the snap, which was the ball that passed over his head, and it was his sound memory.”
“And Ray’s team responds to the snap sound,” added Barker. “And you will hear it pretty much during the movie. And when there is for a moment they would turn and fire and fire. And that would be the key. So when there is a volume of fire from the American troops, that was when they moved. It was always short, sharp taps of the weapon.
At Mendoza’s request, the realistic sound effects that were stirred through the PA system during photography to improve the realism of the actors were provided. “At the first time (Mendoza and Garland) they did not let them know that the shots or bangs or explosions would happen,” Barker said.

Freemantle and Barker went to Czechoslowakia to shoot live rounds of ammunition and composed each separate element in the shot. They shot living ammunition through metal doors and through walls. “Everything was how it would be and the sounds from the aircraft that came above and shooting,” Freemantle said. “We actually had previous recordings of the right jets, so we were lucky to use these sounds again. But from Ray’s memory was the sound of the sonic boom. It was when you really know the effects of that noise. And Ray said:” I think the sound is a little premature. “From his view of where they were, it was all the way to that kind of detail.”
It all started with the surprise of the IED explosion in the apartment. This was the concise blast that set warfare in motion. Each soldier responded differently as if they were in their own individual fog.
“Again, Ray gave us such knowledge: a grenade had a certain crack sound or a larger boom sound for IED,” said Freemantle. “So we gained good insight into how it sounded. And then we started building different layers to do it. So it was to get the really tight sound on IED effect, the metal and the phosphorus. And the weight, how the sound wave would hit them and the air pressure as well, not just at that moment, but it was also when the weapons shot.

“The perception of how they heard these things was quite interesting,” Freemantle continued. “So to make it out of the perspective not only to look into the movie but how each one perceived things as it happened was part of a massive thing.”
When it comes to the mixture (especially for Dolby Atmos and IMAX), it was a special immersion where each sound was created with precision and accuracy. There is actually a scene where Mendoza is overwhelmed by the radios that come at once while they are under attack. “They are on the left, then right, left, right, left, right,” said Freemantle. “Basically, it is from within his ears and it drives him crazy.
“You could say that there is no music, but that moment does a musical thing,” continued freemantle. “It carries you with the radios that fly around and all to that moment of silence again. It took a long time to get to that point. And a lot of work in advance to make these radios work.”
