1. In plently of Alien Media, the ALiens are killed with farily standard fire arms, Chiefs weapons should do the same thing.

2. What proof do you have that his sheild went off when he went in the water?

3. Predators weapons are Acid proof, in AvP Lex stabbed an Alien with the Predators spear and guess what, the spear was not affected by the acid. You seem to be missing my point, my point is there are materail that the Aliens blood won't melt. Chief armor is capable of wistanding plasma weapons, so it's entirly possible that his armor is corrosion resistant.
