Happiness is:

[Cross]

Happiness is having a 17 pounder well dug in, in cover, on a distant hilltop. Handled by a cool and professional crew, who waited until the oblivious Germans were all sorts of exposed before starting to 'fire at will'.

That AT gun got 9 kills without even taking any casualties; and won me the battle; but only after the Germans had over-run and completely anihilated an infantry company.

Misery is having an infantry company supressed and scattered by artillery, taking casaulties, and being attacked by a well organized mix of armour and troops. Not a thing you can do...

[PatG]

Happiness is when your recce tanks spot a 2 companies of infantry (the enemy's main force) moving fast over open ground right under your lone gold spot. Nothing like breaking force morale to end a game.

snipers in a night assault; especially when the 25 pounders open up on where he was two turns ago.

[desh44]

Airdropping a string of scouts and snipers behind the line and having them take out a couple of batteries of field guns

[Marek_Tucan]

Happiness is your motor scouts with light tank support finding an unguarded spot and penetrating to enemy gun and mortar batteries.

[Artur]

When your opponent is cooperative to your battle plan .
(Sometimes this also must be very suspicious...)
