This looks awful. The rifle keeps going up and down while it is walking, no stabilization and they didnt show any accuracy data. You might as well ducktape a rifle to a roomba.

Aiming at targets far away is very hard. Even if it has to stop to shoot, how does it aim? By moving the body of a giant robot dog? That doesnt seem it has the sensitivity it needs. If the rifle is moving that much during walking, how can you accurately aim at anything, since you dont know where the rifle will be aiming when you stop? The camera seems to be on the robot and not on the rifle and everything is jiggling.

Also why even use a full goddamn rifle? You wont have a human holding it, you can just use a modified barrel basically. Are they not embarrassed by how bad this looks? Are they so clueless?
