Actually the most common type is still the non guided variety.
Typically a small submunition with a HEAT charge capable of penetrating four inches or so of armor and a pre set fragmentation pattern for soft target, with a 155mm artillery round carrying several tens of them.
Such munition rely on numbers to achieve coverage and lethality, with the HEAT warheads penetrating the roofs of most
AFVs out there (and the engine decks of those few with reinforced top armor) while the storm of fragments kills anyone exposed.
A lot of specialized HE submunitions also exist, as antiarmor capability is both expensive and not always necessary.
