Flanking. I know this is a very good thing, but I don't know why. I don't want to flank someone without knowing why I'm doing it
and what kinds of advantages it offers me to do so.
Thanks
Ok, basic tactics: a good way to prevail in
40k (or other wargames) is to concentrate your forces. If you can fight 500 pts of his army with 1000 pts of yours, you will very likely obliterate his 500 pts without losing very much of your own force. Then, you can turn the remaining (say 800 pts) of your army onto the *other* 500 pts of his army - again, you'll inflict much more than you'll lose.
Flanking is a very good way to accomplish this in one of two ways:
1) Refused flank: If he's spread out, send your entire army up one flank of his army. His units on the wrong side will be out of range / have no
LOS and have to move to bring their weapons to bear - by which time you should have wiped out the flank you aimed at. Obviously, this works better if you have more mobility than he does. Also, choose his flank that has more long-range weapons to be the one that you aim at - his other units' guns should be out of range.
2) Surrounding and separating: If his forces are concentrated, send a few choice quick and deadly units around one or both flanks. Aim them at his expensive and fragile units that he keeps at the back (ie send multimelta attack bikes against basilisks, etc.). He can either lose his expensive fragile stuff, OR he'll have to split up his main force and send some to deal with your flanking unit. Guess what? The rest of your army is now more concentrated against his main force. This tactic works well with deepstrikers too.
There's also the notion of "rolling a flank". Due to the way Close Combat blocks
LOS, and the consolidation rules, you often only need to get a small amount of dedicated hand-to-hand specialists on the end of a flank of a static army which is poor in
CC (classic example: Dark Eldar jumping on an
IG gunline). The
CC specialists should be able to attack a unit in their own turn, and either wipe them out + consolidate into the next unit, or stay in
CC during the opponent's turn if they don't massacre. Either way, the rest of the gunline can't shoot them in the gunline's turn. Repeat next turn, chewing your way one unit at a time along the gunline. If you tried this in the center, a "spearhead", you might get swarmed by most of his army and outnumbered (even guardsmen can deal a fair bit of damage, if 40 of them charge, especially with "No Retreat" outnumbering wounds against Fearless /
ATSKNF elites), whereas by attacking the flank, he can't bring as many guys to bear at once.
The spearhead can be great, and can shatter the center of a spread-out force, locking a huge
CC which blocks
LOS from one side to the other - but you have to make sure you dedicate enough of your own forces to hit all at once, or it can backfire. Rolling the flank is much less risky.
One final note on vehicles: many
40k vehicles have much weaker side armor than front armor. Being able to have anti-vehicular guns aiming from multiple angles, such that a vehicle's side armor is exposed to at least one, is a great way to improve your chances of popping them. See: lascannon or autocannon sentinel deepstriking.
Hope this helped!
