Tumbledown (1988) was pretty good

The Falklands conflict played out while I was at school. It was glamourised for that younger age group to some extent, but even at that age there wasn’t much gloss to be put over why was an entirely horrible conflict. In between some daring missions (Vulcans, commandos non St George’s Island, the fascination with the danger of Exocets and Harriers vs Pumas(?) ) there were boats and submarines sunk with the loss of many lives, and often poorly equipped soldiers battling as much against the elements as each other.
