Which is terrific because it’ll get you out of the range of all the wooden shrapnel that the tree-turned-frag-bomb is going to be throwing around. Guess what projectiles mean? Exclusion zones, baby! I sure do hope you love calculating and drawing those on maps, you’ll be doing a lot of it. And don’t think you can just draw it and not cordon it somehow, nu-uh.
Apart from the extremely time-consuming nature of explosives work (because splody shit is dangerous), the waste of a lot of wood per tree, and the cost of all of this, it’s definitely a very convenient method. Would be super fun though, if not for all the zone-drawing bullshit and safety-schmafety
