What 3 companies should I buy If I want to be as accurate as possible?

"Accuracy" is unfortunately determined by country, time period, location, etc. You also have 200 unit core limit IIRC. You can try and be as accurate as you can, but that can just as easily be replaced with "this works well for me." At the end of the day Steel Panthers is a game, and should be played as such. If you're in a PBEM game with someone who really wants to recreate a historically accurate scenario then it would probably eschew both players to be both aware of this and have a good insight into the nations they're playing and the time frame and location (as noted before). Otherwise its pretty much down to a likely gentleman's agreement not to buy only on-map MLRS batteries, and back to what you feel comfortable with.

You're not limited to three companies. A quick experiment showed that with only buying cheap infantry companies I could easily buy 10 companies worth, and hit the 200 unit limit before I ran out of credits.
