That was another thing I forgot to put in the original M811 post, not only will it be a massive almost stationary target, but it won't have anywhere near the reloading time of any other tank in BL. I'm guessing 10-20 seconds will be good, considering it fires a 150mm Gauss round and there are no automatic reloading systems.(Electronics will short out when main gun shoots.)
Edit:
Oh, yea, moar progress, about 95-99% complete.
