I have 2 Chinese human bomb models and came up with these rules to represent them. I'd welcome any comments.
Human bomb
Basic - 5 pts
Raw - -1 pts
Bomb - 25 pts
Total - 29 pts
Rules - Units formed from 1 model. Follows normal infantry rules up until you decide to detonate the bomb. To detonate the model must have a charge order. After the move is completed place the artillery template, 4"/100mm, over the human bomb model, with the human bomb model in the middle. Any models who's base is touched by the template must roll for damage.
