Do note, we're not humans or even humanoid aliens. I think we're ant like, and thus have an exoskeleton. (No idea how we look though, ) No fear for bees.
Additionally, I don't think we, as a species, know the concept of surrender. Then again, I didn't know that we as a species were terrified of walls.
We don't have fear of bee's or wasps but we still don't want our peoples eyes stung out..however Xeno eyes are different. They can be stung out in the most brutal manner possible.
0) And how is being covered in mud going to help you when the wasps go for your eyes...
1) We don't know if wasps even exist on this planet.
2) Xenos wear extensive body armor. This is, for them, an alien planet after all. And especially with our presence, they will keep their full suits, which including vizor, gasmask, making wasps a non-issue.
3) Xenos shoot much farther than we can throw.
4) We have no ways to apply your plan in a situation where it would be even remotely useful. We encounter them in 2 locations.
a) Xenos are within their walls. [Attacking = Suicide]
b) Xenos are outside on patrol [2 situations]
a) We can't get close enough to throw [Attacking = Suicide, especially for workers]
b) We can get close enough to throw. [Meaning we can also get close enough to eliminate their patrol]
I have nothing against complicated plans, but they must be better than the standard
CHARGE plan.
