Firstly I strongly advise that you install the Falklands_1982 mod by eburger & team.   http://combatace.com/topic/74604-sf2-falklands-mod-redux/      
Two new versions of the Falklands/Malvinas terrain.   Hopefully most of the issues with the original are now sorted, coast lines have needed to be changed here and there and the terrain itself is much more uneven with more pronounced hills and mountains, two seasonal variations are included.   Please read the readme....it really does have some useful stuff in it.   Many thanks to eburger & the team that worked on the original mod.
