How do you go to battle?

[RightDeve]

I think wargames should be done with deep thinking and planning.
Especially in SP, it's "a must" for me to conceive the plan carefully.
It often took me very long hours to set-up my battle, force composition, force disposition, general strategy, and common tactics used for a battle.
It'll be more severe when fighting on urban warfare, where there's no clear landmark, reduced visibility, and tightly compressed forces (1 Coy for a single block, say).

I have to decide: whether to use SMG as a main weapon; heavy off-map or heavy on-map arty; mech or stationary arty; 1 Coy of tank or 1 battalion of SS inf; the perfect diverging of support weapons; where the enemy might land his barrage; where the enemy is likely to deploy his forces; when to commit reserves; to exchange quality over quantity; the availability of Geballte Ladung or PzHandmine on a squad; to use Sdkfz 251/1 or Opel for mech coy; to use 1-barreled or 2 barrelled MG; MG34 or MG42; where the forces should join to bolster the attack; where is the perfect place to do overwatch; whether this Coy should be attached with tank or not; whether my tanks should carry Nahverteidigungswaffe; whether my forces should use the road or the forest to advance; to buy a sniper with Fire Control 10 or 20; Kar 98Kurz or StG-44.................................................bla bla bla
AND WHOLE LOTS OF NITTY GRITTY OF WARFARE indescribable...

Somehow I feel really exhausted to think up those things... But I can't avoid that, "IT's A MUST" = As I think, SP ain't an RTS, and being a Turn-based game, it's not fun (and surely disastrous) to just throw away your forces to be slaughtered by your opponent.
It's a GREEAAT relief to see my plan works well. But also it's a good feeling to FINISH that damned-long "Set-up phase". I think it's a NECESSARY EVIL!
It's a real good feeling to finally test the mettle in a " > 0 turn " battle.
But that ingenious plan "OFTEN" worked very contrary to what I want, a waste of brain... "The more you plan, the more likely you'll be slaughtered", one say...

So, what about you guys? Are you tired of staring at those thousands of toys on the purchase screen?
