Fragmentation, incendiary and anti-armour / anti-armor hand grenades

How a hand grenade entry is written in a tender annex

The M-75 and M-84 quote a plastic body with steel balls of 2.5 to 2.9 mm and of 2 to 2.3 mm; the BRZ quotes a steel body holding 530 g of thermite mixture; the TG-1 quotes a cylindrical aluminium body holding 0.3 kg of thermobaric mixture. Mass, overall dimensions and fuze delay complete the entry.
