Act 1
Secondary: Flare Gun/Grenade Launcher.
Primary: Bolt Action Sniper/Draganov Sniper.
Special: RPG/Flamethrower.

I utilize Gas/Explosive/Bullet ammo dumps equally. No matter what I find I can use it.

The Flare Gun Rocks! Single shot kills, Stops a Vehicle dead, and creates fire and tons of it. Crouch and shoot and u got a fire wall. It's a grenade launcher and flamethrower in one tiny unit. Don't leave home without it.

Grenade Launcher: ok that stops a vehicle dead :) I'll take it over the flare gun any day.

RPG: While u wait for the grenade launcher.

Flamethrower: I dont leave home without it. Once the RPG is replaced by grenade launcher. I equip the Flamethrower. The ultimate spray and pray. Throw the sniper rifles away.

Act 2: (I'm only 80% through it)

Secondary: Flare gun or The explosives with detonator.
Primary: That Heavy Duty Grenade Launcher.
Special: Flamethrower.

I do the same thing I did in act 1 but with devestating power.

I snipe with the grenade launcher. Soften the Base. Take out vehicles. Rush in, flamethrower blazing and burn the place to the ground. Place a few strategic Explosives and move on to my next objective. Complete my primary objective using devastating force in record time. Prepare to return home.

Worst case scenario, I used all my ammo, I was reckless blew up ammo dumps. I used up all my syringes, I was reckless and ran through flames with my flamethrower blazing. And the base I need to pass through has respawned.

Solution A: Hop in jeep, pedal to the medal back home. When I get to the respawned base I detonate my carefully planted explosives and drive right through. No pursuit, no problems.

Solution B: I still have that flare gun. Respawned Base, No problem. From a distance I set the whole base ablaze. Ammo dumps and jeeps blow up. Men burn and scatter. Fire prevents approach or retreat. Pedal to the medal and sail right through.

Final Note: my Machine gun? It's on my Assault Vehicle. Flare up that base and mow em down with the Vehicle gun while they scatter.

Now I've got a decent midgame loadout:

Primary: AR-16

Secondary: M79 Grenade Launcher

Special: Dart Rifle

-each notch on the leaf site is about 80m (so if you had an enemy camp 240m away you would go up about 3 notches)

- go in a field/desert and pace out 80m (each step is a meter) mark this spot with somthing like a truck go to high groud and learn the distance (i use my map to help me remember the distance)

- after you have blown your desired target to smitherines pull out your sniper and shoot the stragalers

- practice makes perfect

-buy the ghillie suite (this helps when the search party comes)

- just because there is a mountain in the way doesn't mean you can't hit your target

- don't try hit moving targets (it's nion impossible)

- when using the mortar remember to change from smoke to explosive rounds by pressing reload

thats about it on mortar tips, if i get any more i shall post another comment
