Unit Overview introduction

I think that the units can be very overwhelming for a new player. Sometimes a simple overview of a unit and a description of its strengths and weaknesses can be very helpful.

For example, you could look at a roach and see that it does 16 damage per hit, with 145 hp, costs only 75 minerals and 25 gas and compare it to the hydralisk that does 12 damage per hit, with 80 hp, and costs 100/50 and just assume that roaches are much better units (which is false). Even if you notice the attack speed difference and realize that hydras do more damage per second, the extra health and lower cost of roaches still makes them seem very tempting. Marauders are another unit that seems like an upgrade to marines at almost every statistic, which proves untrue in real games.

Another example of a common confusion is how to use zerglings. They tend to get slaughtered if you just charge them into huge packs, especially without upgrades.
