Your own game happened happened to catch the lowest level talon co. in the leveled list, which was like the staff sergeant and stuff.
I checked in the GECK to see what health level etc. they had and the staff sergeant in particular was a bit low. But if there's a flunkie there, not sure what you're seeing.
I uploaded a version of NG which has the flunkie set for 240HP or so at level 9, and the staff sergeant as like 245 HP at level 16. Those particular ones aren't supposed to be bosslike enemies, they happen to be the lowest denominator of their leveled lists.
You might check the new .esp and see if it updates the lower level talon co members for you - http://www.finhosting.fi/~fallout/downloads/FoesReworked-NG-HARDMODE.esp - at least then we know you don't have a load order issue. Although looking at the mutants would tell you that for sure, the lowest leveled mutant should have 400 HP and it goes up from there.
