I also have to give credits to the Imperials for both their guerillia ambushes in the forrest area and the idea with the trenches, though the trenches have been meant as a device for hiding and not as an tank obstacle. Still, trench-tactics are really modern afterall. And it worked, as they created confusion among the JSDF. Yet still they underestimated the power of thee JSDF's information network. They can magicaly talk to each other. They created maps of the topography BEFORE attacking. And yes, they could have used thermography as well, but I guess the JSDF felt, they needed some kind of handicap or winning no fun, or something along these lines...
I excuse those stupid forrest generals by assuming they couldn't imagine the JSDF (a force that already wiped the floor with their armies before and showed incredible economic feats by their standards (in other words: are filthy rich/have seemingly endless resources)) couldn't organize accurate maps in the weeks beforehand? Maybe accurate maps are rare in their world, yet still. Okay. I can only excuusee them by so far, taht the guerillia tactics was indeed the best choice.
But no excuses for those jerks in the open terrain on that hill. They take the cake. "What does it matter, if it doesn't hit?" True, but it did hit, didn't it? Even a close impact with the heat, the shockwave and the debris (that double as shrapnels) is enough to count as hit. Poor information situation aside. Those were generals. They should have been briefed about "explosive magic". It's funny how that guy, that went into the shelter, made better use of "What does it matter, if it doesn't (directly) hit (the shelter)?", than the guy who acctually said it. At least that one had some protection from the flying debris. My guess is, he still lives.
