There are a total of 16 training missions and the final six are really tough. Here is a basic outline of all the training missions:

1) THE QUICK AND THE DEAD
Type: Speed Trial
Gold: 00:55:00
Difficulty: Normal

2) GUNSLINGER
Type: Shooting Range
Gold: 01:00:00
Difficulty: Easy

3) STANDOFF
Type: Survival
Gold: 03:30:00
Difficulty: Normal
Method: Stay at the same place you start on. There are 2 ways for the enemy to enter, you must guard them with your life. The enemy only sends Miner ATVs and Rover Flatbed that can be easily destroyed by a Medium Tank.

4) METAL-STORM
Type: Annihilate
Gold: 02:20:00
Difficulty: Hard
Method: This mission all depends on your mines. Use mines as often as you can as they can 1-hit destroy the enemy. Fire from afar instead of being close to increase your accuracy. That's all I can say about this mission. 

5) BADLANDS BUSHWHACK
Type: Survival
Gold: 03:40:00
Difficulty: Normal
Method: As soon as the mission starts go to the right side of the map (below the Item spawn-er). In this position enemies can only approach you from above and below (mostly from below). When the Air Mines spawn above you take it and put one right on the Item spawn-er then return to your previous position. Sometimes an enemy will appear where you put your Air Mine and when he appears press to detonate the Air Mine and kill him before he hurts you. Re-Do the steps until it's over. 

6) SNATCH AND GRAB
Type: Speed Trial
Gold: 01:20:00
Difficulty: Easy

7) HARD TARGETS
Type: Shooting Range
Gold: 01:00:00
Difficulty: Easy

8) THE BRIAR PATCH
Type: Annihilate
Gold: 02:40:00
Difficulty: Very Easy

9) BADLANDS SHOWDOWN
Type: Survival
Gold: 04:00:00
Difficulty: Hard
Method: I found it easier if you run away instead of defending. It will take a few tries but you'll make it, just stay away from the enemy firing zone. More enemies will spawn over time (Max 5) most of them are Combat Walkers which are slow and easily avoidable. You could get The Running Man using this method but if you're having trouble at the end feel free to start firing for your life. 

10) WHEELS OF FIRE
Type: Speed Trial
Gold: 01:30:00
Difficulty: Easy

11) TOXIC TAKEDOWN
Type: Annihilate
Gold: 01:45:00
Difficulty: Normal

12) COLLATEAL DAMAGE
Type: Shooting Range
Gold: 01:10:00
Difficulty: Normal

13) COLD DAY IN HELL
Type: Survival
Gold: 03:10:00
Difficulty: Easy

14) QUICK AND DIRTY
Type: Annihilate
Gold: 02:50:00
Difficulty: Normal

15) HOTHOUSE
Type: Survival
Gold: 04:20:00
Difficulty: Hard
Method: This one is tricky but can be easy if you follow these steps: A few seconds after the mission starts Mines will spawn on the left side of the map; take them. After that go to the top right corner of the map and stay there; it'll be your defending place for this mission, enemies will only approach you from below. If your health gets low grab the Shield below you and drive to the left side and you'll find Health (It won’t appear if you don’t get the Mines at the beginning). Then go to the upper area and grab the Singularity Bomb just in case you need it. Return to the defending position and stay alive. If you do these steps you shouldn't have any problem.

16) LAST FURY
Type: Annihilate
Gold: 02:15:00
Difficulty: Very Hard
Method: This mission depends on your accuracy, use of items and your bonus kills. There is no easy way to do this, just memorize the enemy locations and try to get as many bonus kills as you can. Use as many items as you can to get fast kills.

Tips:

• Press  to change between Stick Fire mode and Trigger Fire mode. Use the one that suits you best.
• Your accuracy depends on how far you are from your enemy; Close=bad. Medium=Very Good. Far=Good
• Bonus kills (Double kills, Triple kills...etc) helps increase the time on survival and lower it on annihilation which can help a lot.

Some take a lot of time to get and some can take very little. For the vehicle kills achievements you have to kill the vehicles while in any vehicle.

Vehicle Kills boosting method:
Game Mode: Capture the flag
Map: Chem Zone
Game length: Doesn't really matter preferably short
Vehicle: Light Walker/Heavy Tank most damaging vehicle for you
Helper's Vehicles: Whatever vehicle the person getting the achievement needs
Damage: Very High
Fire Rate: Increased
Vehicle Speed: Increased
Extras: Boosting partner should have preferably more than 1 controller in the game.

How to boost using this method:
You should take it in turns of whose getting the medals/achievements as in when player A has got all of the medals/achievements it should be Player B's turn to boost. This saves swapping controllers around after every game. So first thing's first player B (Not getting the medals) should start an online game with 3 (or 2) controllers playing as guests then invite player A and start the game with the game settings above. Player A (Getting the medals) should then drive to player B's flag zone and keep killing his vehicle's. The great thing about this method is that the vehicle's should always spawn around you and there is no time limit. You can rack up the kills very fast this way.

Using this boosting method you can get the Tank Killer medal, Walker Killer medal and Light Vehicle Killer medal. After player A has got these he can then boost flag captures and wins using this game mode. It only takes 2 flags to win so each game should take you around a minute to win. After about 2-3 hours you should have all of the medals and maybe even all of the online achievements as well.

Go on Standoff (the 3rd training mission, the first Survival one). All you have to do is to run in circles around the rocks for 3 minutes and a half. Items are allowed (so you can run over the mines and the repair power-ups, the trophy will still unlock). But you must not fire your weapon. An enemy will spawn after 30 seconds, another one at 1:30, and the last one at 2:30. This is very easy in my opinion and I got it on my first try. Only when you are low on health pick up the repair tool because it doesn't disappear.

Please refer to the 'Faction Leader' Achievement. 

*Note, after getting this achievement you unlock 1,000 salvage to use on Red Faction: Armageddon*

You will need 55,600 exp to reach rank 20. Each training mission contains 1,500 XP; out of it you get 500 XP if you earn Bronze, 1,000 if you earn Silver and 1,500 if you earn Gold. You can not repeat a mission to earn more than 1,500. So that's 24,000 XP out of the way. You could try and unlock this achievement while boosting gold medals but you may need a bit more XP and a lot more if you don't plan on boosting the Gold medals.

Player B (Not level boosting) starts up a game with 3 (or 2) controllers and invites Player A and then Player B sets up the game settings as above and starts the match. Player than continually keeps killing Player B as fast as he can. Player A should keep picking up items until a Singularity bomb spawns (looks like a purple ball) and then ask Player B to group up 3 of his vehicles and use it on them. Player A must make sure his own vehicle is well away after detonating it or else he will get killed and 'The Black Hole' achievement won't unlock for some reason. It should take you about 1 hour to get too level 20 this way with about 3-6K XP a match.

*Note, after getting this achievement you unlock the EDF gun to use on Red Faction: Armageddon*

You will need either 3 other players to boost with for this or 1 person with 3 controllers. If You have 3 controllers you can let them play as guests and they do not need a gold account. Please see the 'Faction Leader' achievement on how to get this achievement easily. To deploy a Singularity bomb press  and then press  to detonate it.

Easily boosted by using this Thread. Please see the 'Faction Leader' achievement for a great boosting method on this. Try not to get too close to vehicles when you are blowing them up because they may take you with them.

Quad Kill = 4 kills at the same time. Best way to do this is by using the Singularity Bomb, press  to deploy it and when you see 4 enemies next to it press  to detonate. The easiest mission type to do this on is an Anihilate mission or a Survival mission. This is very easy to get and shouldn't give you much trouble. Remember though this must be done in Training Missions.
