Fragmentation grenades weigh a pound apiece. We attached them to our equipment by inserting the handle through a ring on our web gear and bending it around so it wouldn't fall off. I tried to carry them so that I could see at a glance that the pins were still there.

Most of the grenades that I used were tossed into bunkers or spider holes to collapse them. Every so often you could get a seconday explosion from something in the hole.
