In a few of the levels, like Irvings and Flaming Dart, you see control towers, where there is a large spawn of something like helicopters, planes, or boats. Well you can destroy them so the vehicles won't spawn. With the Americans use the LAW rocket 67. As the Vietnamese use the RPG. You can also use C4 and other vehicles like planes and helicopters. You get your weapon of choice and find the tower, it is on the mini map like a bobby thing. You find it then look and see if there is any ammo, if there is you shoot at the pole closest to the ammo, then reload, it takes around 16 shots for it to smoke, then 7 more for it to blow up. Once you do that you have two more left, then you enemy is almost powerless. You don't get any points for this though.
One type of the engineers on the Viet Cong Faction are equipped with shovels. In order to use the shovel, you must find a dirt mound with a shovel stuck in it. These dirt mounds are spawn points.
When near a dirt mound, press G. You will pick it up. Now, you can put the dirt mound spawn point anywhere on the map by selecting shovel again.
