Thermate. Used for destruction of equipment.

AN-M14 TH3 incendiary hand grenade
The AN-M14 TH3 incendiary hand grenade is used to destroy
equipment. It can damage, immobilize, or destroy vehicles, weapons
systems, shelters, or munitions. The grenade may also be used to
start fires in areas containing flammable materials.
(1) Body -- sheet metal.
(2) Filler -- 26.5 ounces of thermate (TH3) mixture.
(3) Fuze -- M201A1.
(4) Weight -- 32 ounces.
(5) Safety clip -- no.
(6) Capabilities -- can be thrown 25 meters by average soldier. A
portion of the thermate mixture is converted to molten iron, which
burns at 4,000 degrees Fahrenheit. It will fuze together the
metallic parts of any object that it contacts. Thermate is an
improved version of thermite, the incendiary agent used in hand
grenades during World War II. The thermate filler of the AN-M14
grenade burns for 40 seconds and can burn through a 1/2-inch
homogeneous steel plate. It produces its own oxygen and will burn
under water.

band (current grenades). Under the standard color-coding system,
incendiary grenades are light red with black markings.
