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.
