With any vehicle (not an AI), there will usually be a squadron of soldiers supporting it. You have to eliminate all the soldiers, either lethally or non-lethally. When the first squad is gone, soon enough backup will arrive. Keep eliminating soldiers until no more seem to arrive within a 20 or so seconds. If you've happened to keep under the radar this entire time without an Alert, the Captain controlling the vehicle will pop his head out.
If you have been spotted, you need to weaken the vehicle by 3 bars of health. After that, you can simply take out the Captain any way you wish. You will then capture the vehicle. Further into the game, more difficult vehicles must be depleted by a minimum of four bars of health before capture is possible instead of three like earlier ones.
If you are playing peace walker battle 2 for the first time it seems soooooooooooooo hard. but if you play it the second time it seems much easier. All you need is the the FIM 43. M60 ,LAW and supply marker. when its about to fire its nuke missle keep shooting the AI pod with FIM 43. when it stops the launch and fights you. when you are out of ammo switch to M 60 and just keep shooting its AI pod. when it jumps into the water use the supply marker to restock because when it comes out it will try to launch its nuke again. fire AI pod with FIM43 when it stops launch take LAW and shoot the AI pod. When you are out of ammo use supply marker to restock. When it turns on that spinning thing on its head don't use rockets or it will use them against you so use M60. it will go behind the buildings and start nuclear launch again but the AI pod wont be able to be hit with free aim so lock on with FIM43 and shoot it till it stops the launch. now the rest is all up to you so I hope my tips helped. :-)
A simple method which involves little sneaking. Simply have a CQC enabled gun and run up behind an enemy. As soon as you get the CQC icon, bring them down to the ground and hold them up. If you time it right, you should have taken down the enemy before they could call for backup. This makes it a lot easier to deal with platoons throughout the field.
During the mission "Infiltrate the Crater Base" you will search different trucks with different license plates for a specific mission related item. However, the other trucks contain special items which will provide hidden easter eggs. They include:
SHINA GAWA (57577) PEACE SENTINEL: Containment of Fish
CENTRO AMERICA (48273) PEACE SENTINEL: Metallic Gears which will make Snake say "Metal... Gear..."
CENTRO AMERICA (63824) PEACE SENTINEL: Mr Kojima will wave at Snake, before being Fulton extracted (Fulton can be heard)
CENTRO AMERICA (64799) PEACE SENTINEL: Mission related item.
CENTRO AMERICA (00000) PEACE SENTINEL: A bunch of Boktai Master Otenko (Boktai character) plushies, which gives of a tune and causes snake to yell out "SUN LIGHT!!!"
CENTRO AMERICA (777) PEACE SENTINEL: A box of poker chips and gold coins.
CENTRO AMERICA (140.96) PEACE SENTINEL: A poster of Mei Ling from MGS1, which will cause Snake to groan in puzzlement.
CENTRO AMERICA (66447799) PEACE SENTINEL: A stack crates.
During the mission "Infiltrate the Crater Base", at the end of the level you will have to search trucks with different License Plates. Search the one with "63824" (Third from the Right). Snake will spot Hideo and exlaim "Mr. Kojima!", to which Hideo will be Fulton'd to MSF. His stats are:
1224 LIFE, 1308 PSYCHE, 1163 GMP, D (R&D), S (Medical), S (Intel). His title is "Game Designer" with a description of "70% of my existence if made of movies. It is up to you to decide what to do with the remaining 30%."
To Unlock Monster Hunter Missions within the game, first listen to all of Chico's Briefing files library. You can skip through these all with Circle; just make sure that the exclamation marks are all gone. These can only be unlocked after completing the mission within the area. This includes:River Valley - Mission 5
Crater Area - Mission 8
Tropical Cloud Forest - Mission 10
Ruins - Mission 13
Mine Base - Mission 15
- The Loch Ness Monster
- Mokele Mbembe
Once that has been done, start either Extra Mission  or , with Snake. When it has loaded, proceed to Playa del Alba and make your way onto the pier after receiving a codec call from Kaz. A cutscene will then start, and afterwards you will have unlocked your first Monster Hunter mission!
