Its actually interesting to consider how hard modern drone warfare would fuck with a 40k force like the guard. What kind of counter do they even have against that? Its not like those big Tau drones that are easy to see. Just imagine every few weeks your Basilisks, your ammo storages, your commissars go boom and the earth military knows of every single position, every single troop concentration and every single force build up you do and they just fuck it with long range missle fire. Unless this is some situation where you can bring overwhelming numbers to the field to just carelessly tank any number of losses that would make even the russians blush, i can see the guard struggling real fucking hard.
