I like to get molotovs because they are the only real way to get units out of a building in the first few minutes of a game. Furthermore, even if your opponent dodges the molotov, it will make his units move from cover (take damage), shoot less accurately while moving (deal less damage), and possibly not shoot at all (if they are moving the away and the models are facing their backs to your conscripts).
Conscripts are also so weak without PPShs that molotovs are really the only way to quickly kill, or even threaten, crew-served weapons like MGs and Paks.
This.
