In Oz, we went through a stage in the 90's where drill colour was gold. Some M30 grenades (normally Blue) were modified to become drill grenades (re-cockable empty fuze mechanism). They weren't that successful.. given as most of the grass in Oz is similar shade to gold..I have one somewhere and will pots when I get back to Oz sometime in Feb
There must be a cricket joke in there somewhere!
