Yes, it happened! 
Scenario:
Royal Marines Company backed up by 8 mortars and 2 Scorpions (Gennorm) assaulting a ridge held by a company of Argentine conscripts with 2 brigade mortars in support (Me).
Rules: Sabre Squadron
Royal Marines came in at about 600 points (Elite, expert training) vs 300 points of Poor Conscripts, with Doubtful higher command too!
Table was relatively open, but then unless you want to fight a night battle (which we should have done, but this is teh first time I'd tried the rules) the Falklands is! Three hills (left of shot) covered the approach to the ridge, which Gennorm would use as cover to advance.

Argentine initial deployment was 3 platoon holding the centre of the ridge

1 platoon holding the left of the ridge, with a rifle team, an HMG and a sniper on the rocky outcrop that pushed forward (seen from British lines)

Company HQ and supporting rifle teams in the centre

2 platoon on the right flank (top)

Sergeant from 1 platoon spots what's coming!

The British advanced under 2" mortar smoke in three groups with the Blues & Royals providing armoured support, this was going to be tense!

However, almost immediately, the Marine centre platoon attracted fire from teh vast majority of Argentine forces, and took immediate losses, immediately!

Their return fire neutralised a Squad Machinegun stand, which would basically keep it's head down for the whole game.

It now became apparent the problem I was going to face, while the Marines could take massive losses, they could just keep going as their morale was so high, if my forces became pinned, they could not shoot as effectively and so my initial lethal volume of fire decreased substantially!
Damn, I hate rules that work with historical accuracy!
The British Mortar battery, and one platoon of British fire was directed for a large chunk of the game at my left flank, where an HMG and rifle had been enfilading the centre Marine platoon from. Their job was to hold up the British advance, they did this rather well!

And that sniper, useless! Couldn't hit a barn door all game!
The British right hand platoon, advancing almost untouched behind their hill

British shots start falling in the Argentine line, and due to their dodgy morale, most never recovered!

After many many turns of trying, the two Argentine brigade mortars finally ranged in on a mass of already pinned Marines from Gennorm's left hand platoon.

This really didn't help them!
Meanwhile, under sustained armoured fire, my right hand (2) platoon failed their morale and decided to seek cover behind the crest line they were supposed to defend! Only by the timely intervention of my CC did they not completely leg it, yet!

In the background you can see the damage the middle Marine platoon was taking!

The British advance

And tripod mounted GPMGs finally clear the rocky outcrop, leaving the way open!

On his left, his advance is also going well, that was an awful lot of firepower to face!

Plus mortars made sure 3 platoon was somewhat crippled, losing their attached HMG and taking turn after turn of Milan hits (none of which did any damage, apart from the Argentine Company's laundry tab)!

Things were starting to go historically, 2 platoon was rallied from with draw to 'Hold' by the CinC behind the hill, and soon they noticed they could see Gennorm's advancing Marines too!
Brisk exchanges of fire and expletives followed!

(British losses can be seen to the rear)
At this point my left (1 platoon) also decided to retire to cover; whilst 2 platoon decided to make for the safety of Port Stanley!

Argentine loses visible on the base line!
Win to the British, but a great game, the lack of morale meant the Argentines, once they started going, had great difficulty returning, whereas the Marines kept marching on!

Love that shot!
