Here are some more soldiers. These ones are the S.A.U. (Specialized Assault Units). Enjoy.
About this creation
First off, the Tier One soldiers : the Heavy Drone, the Hazard Zone Cleaning Unit and the Mechanic.
Here is the Heavy Drone. Each one is controled by operators in the underground base. They are fully armored and armed with an assault rifle and a grenade launcher. These cost around $60 000 so when one gets shot and killed, it's bad.
Now the H.Z.C.U. He's equipped with a hazard waste pulverizer and a regular assault rifle. They are lightly armored but fast on there feet, smart.
Third, the mechanic. He follows the fireteams to repair there gear and vehicles. He can intervene in combat if needed.
Right here are the Tier Two units : The Pathfinder, The Marksman and The Black Ops Soldier.
The Pathfinder is also used as scout. They go out to find ennemy bases and installations to report there location to the command. They are equipped with a heavy assault rifle, zoom lenses and infrared vision goggles. The Pathfinder is my personal favorite soldier.
Second, the Marksman/Sniper. These guys are armed with a long range sniper rifle and a medium range assault rifle. There effective range is of 1000 to 1500 meters (1093 to 1640 yards). There armor is very light so they can change position very fast.
And finally, the Black Ops. They work at night to surprise and silently kill the ennemy. They have a LMG or an Assault Rifle with a SMG as sidearm. They are heavily equipped with grenades and devices and are hardly trained.
