I have difficulties in satisfactorily including RBS into a good strategy as well. Both Dennis and Fish have suggested building two strelky prior to upgrade to RBS. I find that delaying any upgrade until 3 squads may benefit from it is helpful. This allows additional time to Stockpile sufficient Mt to pay for squad upgrades. I find that delaying the arrival of CS until the PPS43 upgrade is available is helpful as well.
You may try this. Plan on playing Breakthrough. You don't actually have to select breakthrough but It will help avoid the temptation to go for NI or FTM and full conscript rifles. IE base your strategy on reliance on Strelky and RBS from the start. To this end try a heavy ing start, T2/T2CS with THS then T1 Strelky, RBS. Use your ings to set up a strategically Placed MG nest and enough defencing to flow the enemy into the MG's maw. 3 Strelky/3 TH seems to work pretty well. At range go the LMG route.
