in fact,it was not only a model work,the trench based on tank file,only in this way,you can use the soldier graph ,if the man killed, the graph in the trench will vanish too.
very obviously ,the detail of RWM6.7B2 is better than RWM6.6,I hope the finished version will be perfect.especially,may be the detail of the sound need to be adjusted,It is a little uncoordinated.
