Titanium and Graphene are Strategic Resources. They are used to build high end troops. Strategic Resources are called SR for short. SR's are wilds at random places on the map, there are only 6 titanium wilds and 6 graphene wilds. They have different icons on the map then any other wild. You can buy a map or build a map from attacking terrorist camps. An unowned SR site has the same troops as a level 10 wild.
If a SR site is owned, then it will have what ever troops the owning alliance has sent to it for reinforcements. In order to take that wild you will have to kill all the reinforcing troops.
Once your alliance has a SR site, upgrade your distribution center in city one and materials science skill to receive more SR per hour. Only city one will accumulate SR. If you reach your SR capacity in your city, move the SR to another city, so that you continue to gain more.
THE MOST IMPORTANT PART OF HAVING A SR SITE IS REINFORCING IT. An SR is like an embassy it only has so many slots, so condense your troops to one wave, that way more of your alliance mates can also reinforce it.
IF YOUR ALLIANCE IS LUCKY ENOUGH TO HAVE AN SR SITE, DON'T BE A LEECH! REINFORCE IT!
