Trivia

 * These vehicles can not be damaged by bullets, fragmentation grenades, or grenade launchers; however, RPGs, Predator Missiles, AT4s, Javelins, and Semtex can destroy them.
 * If a player attempts to damage this vehicle with the GP-25 or the M203, the message saying "Frag grenades cannot damage this vehicle" will appear.
 * The BTR-80 is incredibly weak against RPGs and anti-armor weapons considering that it is an armored vehicle.
 * Destroying this vehicle in a Special Ops mission, such as Body Count, will count as a "Mega-Kill"; 400-8000 points, depending on the way the player destroyed it.
 * In "Wolverines!", if the player stands right in front of the BTR, it will not shoot the player.
 * In "The Enemy of My Enemy", if the player goes near the BTR's door, the player can see that there is no room inside it.
 * The BTR mounts a secondary machine gun opposite the main 30mm cannon; this doesn't seem to have any function in-game, and the barrel is sometimes missing.
