Death Korps of Krieg would defeat any military force in a battle on land

I... I had no idea that my opponent would be debating in terms of a the table top boardgame of WH40K, I suppose since his arguments and points reside in the table top game, then I will debate on those grounds as well. When it comes to the table top game, and the Krieg and the Tau clash, it truly depends on the commanders and the forces in which the points have been divided. I would see that the logical choice in any Krieg player's army would consist mostly of Death Riders, large Krieg squads, Hyrda AA tanks, Basilisk artillery tanks, and a couple Warhhound titans bearing an autocannon and an incinerator arm. Despite the weakness of the Krieg armor and the low penetration of many of their guns, the sheer number of them would overwhelm whatever fire warrior squads the Tau side could bear. Death Riders and their large move distance and their explosive lances would do much to close the distance and destroy nearby vehicles and infantry... however, in the sense where you have camping fire warriors with pulse rifles with 24 inch range, the Krieg still come out first. Basilisk guns go up to and beyond 100 inches, allowing those tanks to effectively pound any squad, vehicle, or entrenchment a Tau Cadre could muster. Sure, the devilfish bombers and Mantas would wrest control of the skies, yet, those Hyrda AA tanks make short work of any airborne vehicle any faction could throw at the Krieg weapons. I do not doubt that many points will be claimed by Tau forces in the beginning of the game, and I do not doubt that when the Tau fire warriors get their defensive lines set up, the Krieg will take casualties. But when it comes down to it, both sides know the forces of the other, the Krieg titans would hit any objective head and use their suppressing weapons to effectively wipe out anything on the ground. Your titan hunters? They'll have to decide between Titans and artillery, which, a smart Krieg player would keep AAs near both. In all honesty, in the table top game, it would really depend on the commanders playing. Especially since in that version, it's turn based. I do not doubt that the Mantas would decimate vast swathes of Krieg units caught off guard, and more than likely, the first few turns on the Krieg side would be dedicated mostly to wiping out heavy Tau units more than charging into objectives and entrenching. Yet, morale wise, the incinerators on the titans and the artillery strikes would deal much damage to Tau forces, casuing morale issues. Which, in the Krieg case, is not even an issue in the first place. With each volley the Krieg commit, Tau morale checks will be taken, and not every dice roll is good, and Tau Fire warrior squads are inherently smaller than Krieg squads. Either way though, on table top, it truly depends on the commanders, their personal strategies, and the map. When speaking off of lore, the books, games, the codexes for both, the Krieg would dig trenches and create lines the Tau couldn't break. Everything would be happening at one time, which is drastically different than in the case of the Table top, which, can only be valid in this argument since the faction you chose was from the same universe. I would like to hear more of your arguments.
