Directed energy weapons shouldn't bleed when they hit soft tissue, after all, the wounds are burned. Now the means of treating laser burns are completely ineffective against beam weapons (after all, it's not a level), so on the battlefield it should be the first to take the conventional means of bandaging, to avoid secondary injuries suffered by the casualty, in the field hospitals or among the rear hospitals, the medics have to remove the burnt tissue around the wounds first, and then repair and suture the broken tissues, except for the equipment is more advanced and less risky, the rest of it is not much different from modern Surgery is not much different from modern surgery, except for more advanced equipment and lower risk. However, it should be noted that some directed energy weapons are radioactive, and may require some means of removing the radiation (in the case of some radiation burns, then I'm afraid it would require extensive tissue repair). Rapid cloning and self-healing foam in Halo is good technology. Also 3D printing to repair wounds in Reunion 2 is a viable technology (it's already available in reality, but it'll take a bit of time before it's clinically applicable).
And in terms of defense, shields are the most widespread method. After all, many directed energy weapons come with high heat, and thousands of degrees is not something that normal materials can block, so there needs to be an equal strength of energy to counteract them (this is the most widely used shielding principle at the moment. Electromagnetic shields should be effective against plasma, but it's hard to say if they can defend against lasers, and it's best not to use electromagnetic shields until quantum technology is widespread, or you'll be doing damage to your own electronics as well). The Forerunner's hard light shield is also a very effective means of defense; this shield combines the properties of both a solid shield and an energy shield, and is a good defense against both directed energy and live fire. However, hard light shields are still essentially energy shields, and can be dangerous if they can't keep up with energy replenishment (fortunately, the Forerunner's energy systems are also relatively efficient). In addition, the Klein force field used by the Sea Mist fleet is also a good means of defense, the defense principle of this stance is based on the continuous curved structure of the Klein bottle, so theoretically it will not be saturated (in reality it will be saturated, but it needs a computer to guide it to release the energy. So the defense ceiling of the Klein force field is not tied to whether or not the energy can keep up, but rather to the memory and processing speed of the computer). Solid armor is not an effective practice against beam weapons. Unless it can be used to counteract the attack through energy dissipation like the Relative Transfer Armor in Gundam SEED (though Relative Transfer Armor is mainly for live weapons, and can defend against beams if the energy is strong enough, it's just less efficient)
