Frags
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.
