they can throw rocks but nothing larger than themselves and not very hard. certainly not hard enough to do any damage to anything.

Only a handful can actually break glass. Mostly only the large species like large Odontodactylids like O. scyllarus (peacock). G. chiragra is a smaller species but also has the hardest hit for its body size of all Stomatopods (although not the actual hardest i think) and can break through 1/4" glass.
