The secondary objectives are all vehicle (fleeing vehicle) related. If you
want to play it safe, destroy all enemy vehicles. Worried about ammo? Don't
forget that you can pick up and use enemy weapons for the job. Also, use
your team as often as possible. The best way to stop the trucks is to get
a good angle on the driver, and take them out. Then you can destroy the
vehicle whenever you get a chance. Just remember, if it must be destroyed,
you have to do it before the next major mission objective, or it won't
count. If you are just doing this for the achievement and you miss it, but
don't want to play through the whole thing again, then you can frag
yourself. It will reload you at the last checkpoint.
Mission 1 - Cajones
Take a grenadier and if you want, overkill with Kamikaze (rocket guy).
However, if you start with the LMG or an EGLM rifle, you should be able to
take out the trucks with help of the grenadier.
The secondary objectives are the trucks that appear on the bridge after the
two artillery guns are down. If enough explosives or gunfire is employed, the
trucks sometimes stop. Set the team to aggressive and charge onto the roadbed
and empty everything on the truck or anything else that doesn't look as
American as the AVN awards. The resulting explosion should erase any rogue
elements of this insurgency and clear the objective.
Mission 2 - Knock 'Em Dead
This one is moderately hard since the objective shows up before the team
arrives at the rally point. You definitely need the 'Quick Mission' version of
the MULE, which gives you the ability to change your weapons kit any time.
Clear the area to the enemy camp (a.k.a., the construction pit). Without
alerting anyone in the pit, take out the ZEUS from the MULE and use the UAV to
scan for trucks. Prioritize the trucks in the pit and you will meet this
Mission 3 - Unpleasant Surprise
The gunrides you can do on almost any difficulty but easy makes the targets
more vulnerable. Not sure where this objective is, but when your UH60 orbits
the enemy camp, make sure nothing leaves (except the objective convoy, which
you need to blast anyway) and you'll cover this objective. Anything marked
Mission 4 - Inferno
The objective seems to be in the last firefight (at the marketplace). Since
there are three tanks you have to deal with, you might need to take an anti-
armor soldier and let the air support deal with the tanks. The truck (just
one) will come into the marketplace plaza from the direction of the tanks.
Simalcrum discovered this by sheer accident when readying for the tanks and
experimenting with the anti-armor soldier. If you and the team are in the wide
plaza taking on the tanks, etc., the truck's presence will be quit visible (to
the left in the 'shooting gallery').
Mission 5 - Inserted Solo
There are three vehicles to destroy for the objective. The first two are the
trucks that come down the hill after getting off the rooftops. Use the
destructive pack satchel to destroy one truck (several retries at the
checkpoint will show you where to place one) and hose the second truck down
with automatic fire -- the MRC-LW-SD can do that only on the easiest
The final truck you need to destroy is in the area with the snipers (right
after getting the MULE). Before you approach the final zone where the
extraction is, you have to pass by a street with some soldiers. A truck will
come out from a side street and dump enemies off before driving away. Use
the 'Quick Mission' MULE to get a ZEUS. Fire a round of your secondary to
alert the enemies and the truck will appear. Zoom in and dust the truck before
it drives off and you get the objective.
Mission 6 - Price of Peace
This is a tough one. After holding off the tanks at the stadium, go to the
Oshkosh and grab the anti-armor soldier and equip your own character with a
ZEUS. You need to have several rocket launchers since there are three choppers
dumping soldiers and there's a lot of automatic gun fire. This makes your own
progression from the stadium to the extraction point hard since you need to
rely on a secondary (no scope) PDW and SMG to drop enemies. Take the gunner
with you so your team can hose enemies.
As you near the extraction point, take out your ZEUS (so you can checkpoint
it), and send the team to follow you. Set them down away from the merry-go-
round and kinda covering one side of the park. You must take on the other
chopper. Who ever has more life (kamikaze or you) will need to take down the
final chopper (not the gunship that blows the merry-go-round) and you should
be successful. Ditch the ZEUS, take a G-36 or what's available, meet the kill
quota and extract by jeep.
Mission 7 - On Your Own
On 'Quick Mission' this is easy. Select an EGLM rifle and blast the mo'fo
truck from the insertion point. Afterwards, be sure to follow up with multiple
ZEUS missiles on the choppers until they drop.
Mission 8 - Failure Is Not An Option
This is a gunride, and the secondary is probably making sure all three APCs in
the salvage convoy survive the ride back to the exit. An easy task regardless
of difficulty. Just blast all the enemy vehicles and there'll be no 'fleeing'
Mission 9 - Get Rosen
There's a truck at the northern camp (after blasting the wreckage) that
doesn't move, and it may not count, but destroy it anyway since you ain't
usin' it. Rally at the Oshkosh and choose a guy who can take out trucks
(grenadier or anti-armor) and take the destructive pack. At the hacienda, the
hostage is in the southwest structure, so clear it (but do not approach the
hostage). Instead, locate the big fat main entrance (Spanish curve style) and
place a satchel on the side of the entrance you can't cover from the roof on
Rosen's building. If you have access to an LMG and brought that along, you can
skip the formalities and hose the trucks down. Blow the satchels on the trucks
and it'll be over fast.
Mission 10 - Who The Hell
A tricky one. You'd miss it if it weren't for the incredible detail of the tac-
map. First off, destroy all the trucks at the hotel. If you happen to have
Kamikaze or simply an MG21 from one of the AA areas, you're set (on easy).
Expect to spend more ammo on medium. Now the cruicial part -- since you need
to destroy all 'fleeing vehicles', you need to know there're two trucks hidden
in a part of the map you need to backtrack to after the Oshkosh rally.
After defending the front of the hotel, you meet a tank and chopper near the
Oshkosh. Use this chance to take on a ZEUS (your A.I. team is too unreliable
for this and you also have a chopper). Once you loadout, look for some stairs
to the right and behind the tank. It'll be next a building and appear to lead
nowhere (or back to the secured blue zone). Quickly go up onto the roof and
get the chopper to you. ZEUS the first truck and that will create a traffic
jam and allow an easy kill on the second truck. If you want, you can use the
chopper to take out the first truck and use whatever weapons you have to take
out the second truck, giving the luxury of using another weapon kit.

Mission 11 - Codename Farallon
Although you want to take a marksman here, the anti-tank soldier Kamikaze is
best for the boss and secondary objective. After clearing out the city, head
to the water treatment plants. Take out one of the plants and choppers will
appear in the middle area (near the three treatment silos at the parking lot)
and drop off people. Use soldiers to team-blast for the objective.
Mission 12 - Shaddap and Do The Job
This is a hard one since you have to skip out on the marksman and medic.
Select the anti-armor soldier and slowly get up and over the hill. If you are
sure of yourself, you can take a ZEUS and use a PDW and the allied marksman
instead. As you descend the hill to the toll booth, an enemy APC will appear
past the gate and give you about 5 seconds to drop it. If you leave it be --
or aren't fast enough -- the APC roars off and you screwed yourself. Good
luck. The Oshkosh after the bridge fight will let you replenish supplies.
There're still trucks and all that while having a tank and chopper around, but
take out the two anti-armor enemies and your vehicles rule the roost.
