Thermite grenade

Thermite grenades are a type of explosive incendiary ordnance used by the UNSC. The flames from the thermite grenade can burn underwater.

Thermite grenades rely on a chemical process between metal powders and oxides to create high temperatures, with no explosion. Commonly, aluminum and iron (III) oxide are used in the reaction. Thermite can reach temperatures an upward of 2500°C (4500°F), and is often used to melt through a wide range of things extremely quickly. However, thermite is rarely used for anti-infantry roles, and is more practical to use in anti-matériel roles due to its ability to quickly disable mechanical components with few ways to stop the reaction.

Thermite shaped charges are also used to quickly gain entrance to locked areas.
