Firebolt And HEAT Family Context

HEAT 758 sits in the Carl-Gustaf 84 mm ammunition family but is defined by its tandem anti-armour effect and Firebolt communication with the M4 fire-control chain.

Item	Role	Source-backed context
HEAT 758	Tandem anti-tank round	Saab lists a 3.7 kg round with 600 m effective range, Firebolt compatibility, and up to 700 mm armour penetration.
HEAT 751	Earlier tandem HEAT round	Saab presents HEAT 758 as a step beyond HEAT 751, adding more penetration and range while keeping roughly the same weight class.
HE 448	Programmable high-explosive round	Saab identifies HE 448 as the earlier Firebolt round, making HEAT 758 the second Carl-Gustaf round designed around the Firebolt chain.
