I had a cool but not so original idea: aliens with many many redundant organs, and a nervous system spread across their bodies. This creates some issues. How do I kill one?
What the Alien is like:
The alien looks like a blob with lots of tentacles covering it. Each tentacle has a eye, mouth, fingers, and a digestive system. There is no heart, or lungs, or other vital organs. The aliens' organs are spread out through their bodies. Their bodies are about the size of a smart car and the tentacles are about 10 feet long. To move the aliens throw out their tentacles and drag themselves forward. By doing this they move about as fast as a jogging human. They are not particularly resilient, but they are wearing sleeves and a “vest” which will stop small caliber rounds and slower shrapnel. Naturally occurring latex will ground them if most of their tentacles are touching the ground. They came to Earth for all of the tasty snacks, which they prefer well done, so they brought lasers to cook humans with. These lasers will torch you if you are under fire for more than 5 seconds.
So I can’t kill it by shooting it through the body. Using only 21st century weapons how should my soldier kill them?
