Surface-to-air missile launcher

Surface-to-air missile launchers, colloquially known as SAM sites, are a kind of anti-aircraft emplacement employed by the United Nations Space Command.

Overview
The surface-to-air missile launchers in UNSC service are large multiple-launch-system emplacements, firing missiles at enemy aircraft. There are two major known variants of launcher, with broadly similar designs;

War-era launcher
This SAM launcher used by humanity during the Battle for Earth. It can load three ASGRAM 10X missiles for firing, with racks of four additional ASRGAM 10Xs often seen accompanying it. Such weapons were in use by the UNSC in Voi and Outpost C9 during the Battle of Earth.

Post-war launcher
Multiple of these kinds of launcher were used by the Office of Naval Intelligence to defend their black site surrounding the site of a recovered dormant Lifeworker terraforming vessel. Unlike the prior variant, they contain three blocks of four missiles.

Halo 3
The Surface-to-Air Missile launcher is present in Halo 3 on the Campaign levels The Storm and Floodgate, as well on the multiplayer level High Ground. It is unusable and serves only as scenery.

Halo Infinite
SAM launchers are present in a scenery role on the Halo Infinite map Oasis. They are also placeable scenery objects in Forge mode.

Production notes
For High Ground, Bungie had tried to have the SAM site AI-controlled, so that when players are charging up the map, there would be a risk of being killed by the launcher. Bungie had its AI capabilities removed, mainly because there was too much firepower coming down on the attackers.
