They got ashore last time and had a “Sgt. York” moment with the Gurkhas. Article states Argentine military has failed to recover from first Falklands War. About 30 years ago! NVA re-constituted itself in less than 2 years, several times. Average Argentinian more interested in drinking and screwing and being seen on HGTV than seeing their bodies penetrated by NATO 5.56...
You are correct. But the Argentine Navy and Airforce were unable to maintain control of the sea/air around the Falklands, and so they in-turn lost.
The Gurkhas are an elite light infantry force. But if you put them in a static defense the enemy will simply pound them with heavy weapons to attrit them. Just a matter of time & ordnance.
