fortunately for Czachiva ( the name for the Falklands ) the Czach satellites as well as radar stations not only from their own land but on their ships and under water. As soon as the invasion force was detected (which would be pretty soon since the force and a lot of troops) the navy would be sent out, armed with compact fire cannons and nuclear torpedoes. Once the ships hit open water, costal forts left over from the last war, would been given the green light to fire their artillery at the invaders, making a haze of hot steam from the heat of the lasers and burning anyone on the deck. amidst the chaos, the naval force would order all destroyers to fire their nuclear torpedoes, each with a different target , which fire from a movable tube by firing a rocket in the middle of the propeller, launching it away quicky before the torpedo actually drops into the water and the propeller (power by the radioactive material inside) would surge on, giving no time to move a big ship and colliding into it, making a decent explosion while spreading radiation to any other ships nearby, causing the main ship to sink rapidly while damaging crew and electronics on other ships causing to either retreat or become sitting ducks for the navy. Any ship lucky enough to not suffer this fate would have to face the coastal forts left from the last war and traverse the rocky shore with snipers littering every settlement and tank patrolling the railways and roads. the Cezh government said if the enemy doses not leave, nuclear, biological and chemical strikes will be fired (about he better tech thing, cannonicaly Czechiva have been making new weapons during the long peace time)
red is invaders and blue is Czechiva i lik my new panzer style tank :D
