As far as we know, Phase Shift Armor only works against projectile weapons, and is inaffective against beam weapons.
If this is true it would seem to have little relevance any more, given that all of the newer mass produced MS like the Zaku, Dagger-L, Windam & Murasame carry beam weapons as standard.

We all know that...but strangely you see they still make alot of effort dodging missles (Ahtrun does a Max Jenius and shoots missles) and machine gun fire. I wonder why. Does your energy reserves dwindle as you get shot more by projectiles?
