improved graphics and sound
weapons:
the weapons are almost the same only you don't have the US anti aircraft rocket laungher anymore but theres a new type of a AKSU-74and you have new grenades wich breaks open if it hits something and then fire comes out its a bit like a motolov cocktail only this is a grenade and heavyer,the spas12 is now fully automatic which is pretty heavy and every squad member has also 3 claymores now and you can also have a makarov wich is an russian pistol.
vehicles:
the same tank as in the first game is back the humv is gone but you now have a landstalker whit a col.50 and an automatic grenade launcher and the person who is just sitting can shoot now. you also have a russian bmp-2 tank wich only has one weapon,a power full MG.
grafics:
the grafics are much better now and doesn't has crappy bullets and explosions,the grafics is the most changed thing if you look at desert storm 1. also the numbre of weapons that you carry are still old school and thats stupid but they changed it in the sequal of the game
