I saw with my own eyes a soldier stung on the temple by this big wasp, where the bone was thin and the poisonous needle of this big wasp was severe, so the needle directly penetrated the bone and plunged into the head. Outside the temple, I could also see the poisonous needle revealing a "tail" and the rest all plunged into the bone.

Comparing the similarities and differences between the garrison forces of our army at position 169 and position 142, It will be found that there are a large number of people in position 169 (a reinforced platoon with a total of 45 people and equipped with recoilless rifles and other infantry powerful assault weapons, after being reinforced by the chemical defense squad, although the total number of combat personnel was reduced by 2 people, two 74-type flamethrowers were added, and the melee and assault capabilities were actually strengthened), The firepower is relatively strong, When the Vietnamese troops attacked here, they sent out strong defensive humanoid monsters. However, the number of people in position 142 is relatively small (only the "15 warriors" led by Li Haixin, And only equipped with rocket launchers, Without recoilless guns and flamethrowers, However, there are simple minefields with anti-infantry mines. This is better than at position 169, If a minefield is also deployed at position 169, Although it is not possible to completely kill the humanoid monster at one time, But it can certainly play a significant blocking role, To provide favorable conditions for the main position to carry forward its firepower and carry out annihilating shooting), The firepower is relatively weak, When the Vietnamese army attacked here, it sent out such small targets. Fast, unidentified creatures like "dogs", To sum up, the defense-strong humanoid monster stormed the powerful position 169, It should not be a coincidence that the Vietnamese army has certain tactical considerations when using "living biological weapons" to attack positions more suitable for its own characteristics with different "living biological weapons" instead of simply throwing themselves into the battlefield at will.
