Mission Oriented Protective Posture

Mission oriented protected posture (abbreviated "MOPP", pronounced "mop") is a term used by Tau'ri military personnel to describe protective gear, often worn off-world when SG teams find themselves in an environment that could be harmful or toxic. Teal'c is often exempt from wearing the garments, as his symbiote protects him from more harmful or toxic elements than Humans.

SG teams carry the MOPP gear in their packs, and are usually seen wearing or applying only the gas mask, however, there are five levels of MOPP protection:
 * MOPP Level 0 - Protective mask worn in carrier, at side. Overgarments, gloves, and overboots accessible.
 * MOPP Level 1 - Chemical agent detectors worn, mask worn in carrier at side. Overgarments worn. Gloves and overboots readily accessible.
 * MOPP Level 2 - Overgarments and overboots worn. Gloves and mask readily accessible.
 * MOPP Level 3 - Mask, overgarments, and overboots worn. Gloves kept ready.
 * MOPP Level 4 - All protection worn.

Instances of use

 * Col. Jack O'Neill called for "MOPP 4" after coming in physical contact with a dead man on the planet Hanka.
