Warhammer 40,000 looks at good battle tactics&training and says, "WTF is this shit?!"
And then proceeds to win by either:
1. Throwing more men/tanks at the problem.
2. Throwing super-infantry at the problem.
3. Throwing wierd non-psyker psuedo-sorcery at the problem.
4. Telling the laws of physics to fuck off.
5. Krumpin' wuteva needs krumpin'.
6. Other.
I stopped at "6. Other" because I didn't want to go through every race. Just most of the ones I like (Guard/Marines/DE/sort-of Chaos/Orks).
