#Kill 2 or more enemies rapidly portable#

As suggested, the sheer damage, the stress and/or the bacteria afterwards can all be enough to kill the organism after. So being sprayed upon will keep damaging long after. The fuel often has damaging properties as well, like boiling while ignited. The reason we can fire that far is because we're throwing fuel, which is then ignited. Although the Geneva convention prevented further development, I'm pretty sure we'll be able to make new more effective fire based weaponry. Napalm was done for large area's by planes as well.

Although it definitely is short ranged, human portable could still reach 40 meters (45 yards) and tank mounted ones 90m (100 yards). Movies and games make it out to be a short ranged weapon. It has been said in other answers, but fire is incredibly powerful. You just fly over with a plane, dispersing a cloud the equivalent of a large cough and watch the aliens shut down from a distance. A 21st century soldier might not even be present on the battlefield. In the end, you can't protect yourself against everything. Some can rapidly multiply and mutate itself, so whatever you throw at it is ineffective in the long run. There's also parasites that can eat organisms from the inside. Multiplying in a body, taking resources, destroying cells, excreting toxins, making the immune system kill the host and more. They can go good stuff, or very, very bad. Viruses and bacteria are present everywhere. poisons can be shot, hid in food (cyanide capsule embedded in each soldier?) dispersed in gasses, liquids or just on the ground and be able to kill. Besides directly killing cells, they can shut down organs or manipulate them to make toxins/degrade materials into (more) toxic materials. Again, nerve agents can kill or disable the nerves. A poison dart can be incredibly effective. Similar to gasses but focussing a bit more on the personally dispensed ones. They can potentially unfocus laser beams, so there's that as well. In addition, you can potentially just suffocate the aliens. This is a huge vulnerability, as the gas can be easily take up into the body and spread. As the aliens don't have lungs and I assume still need oxygen to live they probably take it up with their skins. You can do corrosive things, or simply poison the enemy. A nerve gas can destroy or temporarily lock down nerve fibres, killing or disabling the target. They can be invisible and odourless (for humans at least) but still have incredible effects.

Using only 21st century weapons how should my soldier kill them? So I can’t kill it by shooting it through the body. These lasers will torch you if you are under fire for more than 5 seconds. They came to Earth for all of the tasty snacks, which they prefer well done, so they brought lasers to cook humans with. Naturally occurring latex will ground them if most of their tentacles are touching the ground.

They are not particularly resilient, but they are wearing sleeves and a “vest” which will stop small caliber rounds and slower shrapnel. By doing this they move about as fast as a jogging human. To move the aliens throw out their tentacles and drag themselves forward. Their bodies are about the size of a smart car and the tentacles are about 10 feet long. The aliens' organs are spread out through their bodies. There is no heart, or lungs, or other vital organs. Each tentacle has a eye, mouth, fingers, and a digestive system. The alien looks like a blob with lots of tentacles covering it. I had a cool but not so original idea: aliens with many many redundant organs, and a nervous system spread across their bodies.
