guards laugh about the performanche from pgrens...while cost the same and need less muni for upgrading and can slow armor
Guards:
-are doctrinal
-require additional 75 muni upgrade
-have completely different profile(aka not short ranged assault squad)
-belong to army that have poor stock long range damage
-come NOWHERE close to AT potential of shreck PGs.
And the biggest difference:
Soviet elite infantry is supposed to become their mainline infantry late game once you lose all your cons.
Ost elite infantry are force multipliers, NOT gren replacements.
