Cabal Heavy Munitions

"Initial reports assumed these were shells for large-scale artillery, but subsequent scouting has painted a more terrifying picture. They're now believed to be powerful explosives for mining and engineering operations. They aren't giant bullets: they're planet-crackers."

- Destiny Planet View

Cabal Heavy Munitions or "Planet Crackers" are Cabal missiles contained in crates scattered about Mars.

Overview
Guardians had originally assumed that they were ordinary shells for warfare against entrenched Vex positions, but later reports showed they were actually explosives for mining and engineering purposes: potentially enough firepower to crack a planetary objects or moons, with such example being that a Cabal Fleet used them to blow up Hive War moons from the inside.

The Goliath Tank is believed to be able to fire Planet Crackers from its main cannon.
