Guards are fine. I do consider them to be the 'safe' option for Russia. Easy to adapt to both AT and AP roles and pretty solid for their price.
The only time I really see Guards beat infantry squads without a grenade is when they have conscript, maxim or mortar support. Reason I say this is the PTSR gun causes the opponent to jump are quite frequently, making them highly exposed to fire from the supporting infantry. Is this possible part of your issue L337?
In a 1v1 situation a full health Guards don't really ever beat a full health PG's if not succesful grenade is landed. The standard grens do alright aswell, and even if you kill 3 members with your squad before retreating you come out ahead in the MP war.
