A little addendum to my post about weapons. I totally forgot to talk about poisons. I only mentioned them in the context of poison darts. But poisons are very widely used in Dune in many forms, including in combat. Knives are frequently poisoned, which means that they don't have to penetrate deeply to kill or incapacitate. As long as they can pierce through armor a little bit, enough to break the skin, that's enough. Though that still requires a certain degree of force. And then there is poison gas. The same stuff that Yueh put in the tooth could be used in large battles as well, WWI style.
And then I forgot to talk about the necessity of recoil. Unless a weapon striking a shield recoils from it, the shield is far less useful. Imagine this: I thrust my sword at the shield, not just a light jab - I'm pushing the blade rather than "throwing" it. Being too fast, the blade is stopped, but it doesn't recoil. I'm still pushing. Therefore the blade immediately accelerates forward again upon being stopped. And because the tip of my sword is now resting directly against the shield, it doesn't matter how hard I push. At the beginning of the push the tip is still slow enough to pass the shield. It would be like thrusting against a concrete wall that turns into jelly when I touch it. So all that the shield ultimately did was to delay my thrust by a split second and rob it of most of it's momentum. Not enough to save the wearer unless they were also wearing good enough armor.
So we have to assume that fast objects hitting a shield bounce back. Otherwise the shields don't work as described against knives and other thrusting weapons. Against bullets they still work perfectly fine. Actually I prefer the non-bouncy shields. They make knife and sword fights much more intuitive and natural.
hmm, honestly a lot of the issues in that video seems more like a HEMA over specialized training problem. can't quite claim the sowrdsmen are "well trained" if they only know dueling against same weapons. and fuck their trashy point system. some of the spear stabs were clean hits AND potentially had enough power to kill/disable though. i will give the video that much. but the rest... sorry but any armor at all even shit low quality leather would EASILY deflect/absorb those. FUCK TRASHY TAP TO WIN POINT SYSTEMS.
I think the issue here is that spears are more dangerous to train in HEMA. If you make them out of nylon like the swords, then the spears become too floppy (as seen with the greatswords). If you make them out of a stiffer material, like the ones in the video, then the potential for injury is greater. I think that the guys in the video were only jabbing lightly on purpose. The little foam tips do little to cushion the blows. Even with protective gear a full power thrust could lead to nasty injuries.
even the guy in your video notes that breaking the spear would make a difference in options available to the swordsmen.
Breaking a spear is another thing that's not as easy as it seems. Most swords aren't good at chopping wood (not front-heavy enough) and unless the spear is couched under the arm or otherwise held extremely tightly, or the cut occurs close to the grip, the shaft will be knocked away and take little damage. And that's assuming a wooden shaft. With plasteel or whatever futuristic material they might be using in Dune, I would rather assume that trying to break the shaft is not worth the effort.
but hmm, alright you've convinced me enough that they could be used on dune. especially since energy shielding and armor are going to be a thing they won't 'need' a hand held shield. so two handing would be done.
Actually I think traditional hand held shields would be almost completely useless in Dune when force shields are used. I'd rather have a two-handed weapon, dual wield, or just have a one-handed weapon and a free hand. Your whole body is shielded, including your arms. You can block with those already. I'd rather have a free hand for grappling then a useless shield.
it doesn't 'need' to hit a weak spot, when using two hands both blade grabbing in order to bash with the pommel. i would think it would bring a level of power above what a one handed mace could do. a two handed warhammer or a halberld like pole arm obviously will do more, i'll give you that one easy. could be an idea to have some smugglers use halfswording and/or two hand blade grabbing pommel bashing though. if i remember right the technique was born from mercs and sellswords developing it.
Maybe in medieval combat that's true, although I'd still rather trust a mace. But obviously any sort of blunt strike is utterly useless against a Dune-style shield, unless it's so powerful that it can knock the opponent off his feet (if shields even work that way). And you will never be able to do that with a sword.
After giving it some thought, I came to some semblance of a possible explanation. What if the BG have been planning to exterminate House Atreides for good? Using their way, not the war/assassinations way of the great houses. No male heir whatsoever, the only daughter married to Harkonnens - that's it, the Atreides are no more. So Jessica's choice would be not just "make a gift for her beloved" but to save an entire great house.
Ok, that would make sense. It is never mentioned that the Duke has any relatives that could take over the House if he dies without a male heir. But then why doesn't Jessica say that? She says she did it out of love for her husband, which is still technically true, but a very weak justification for such a serious matter.
But that leads me to another question. How then did the BG ever hope to get Leto to marry off his daughter to the Harkonnens? Obviously there's the enmity. But if on top of that it also means that this marriage would end his line... I think he would be far more likely to agree to such a union if he had a successor. Because without a son and no male relative, the daughter could become Duchess. A precedent for this possibility already exists. Irulan is designated to take over her father's throne. So why would Leto agree? I guess the BG could find a way. Maybe assassination?
