Digger really doesn't even want to dick around with the doberman, which is NOT the size and weight of a dog, nor does he want to 'waste' a couple of the decenders on it. Devoted's attachment to it is understandable, and if it was fully funtional it might be worth getting down there to help hold the fort, but it is jury-rigged to move at the moment, and Digger has no sentimental attachment to it.
I have carried a Squad support M60 (which I have always assumed is equivalent to an LMG), it is heavy, plus ammo and a small vehicle to move it around, we are talking at least two decenders for weight, if they don't need a third for configuration I would be suprised, remember, like Digger said, the decenders were built with (meta)human rescue in mind.
OOC I think it would be sweet to somehow salvage it, but it is a paperweight at the moment.
