Solid replies from you guys, thanks for the info. I also want to know what's the difference between partisans and conscripts? In my games I have found conscripts to be much more rewarding to use but what situation should I use partisans?
Since their nerf a while back Partisans are almost never worth it. Yes the inital shock value of partisans coming out of a building behind support weapons can be helpful but after that 30 second period Partisans become pretty useless and are incredibly weak straight up combat units. They also required a doctrine in a faction that notoriously relies on its doctrines much harder than other factions.
Cons are basic mainline infantry that scale decent with the 7 man upgrade while partisans are cheap cqb infantry that won't hold up well in a straight up fight but are pretty good at flanking support weapons with infiltration.
If you really want to go Partisans then only pick them on a map where their infiltration it useful and its a cqbish map. Don't get too many Partisans though because it'll fill your popcap up with really poor scaling squads that will cause mp bleed.
