In the work of movie and TV of many reflective war subject matter, the soldier that can see China is legionary binds grenade of a few Mu Bing together, with the occasion of the blockhouse that will atttack the enemy and tank, panzer.

The attention sees the detail of the depict in drama of these movie and TV, it is the lead that plays that intermediate grenade only commonly OK, explosion of a grenade can detonate other grenade, not was necessary of a root go drawing a line, want, the explosive incident of grenade has a few seconds only, want a root draw a line, had not pulled exploded.
