Army Men 2 - Act 1 - Hard Difficulty

Welcome to my walkthrough of Army Men 2! I will be playing hard difficulty settings in this campaign so I will try to win without using losing any troops & uncover secrets as possible. No manual saves have been used. Squads can be upgraded by gaining XP.
Act 1 Missions:
Map 1 - Kitchen (0:20)
1. Elude Tan commandos. Proceed to a Safe Zone.
2. You have reached the safe zone. Find the portal that will take you out of this strange territory.
Briefing for Map 1:
Burners are very hot! Be careful, soldier!
The large black knobs appear to control the temperature of the burning coils.
Hold down the SHIFT key while clicking LMB to fire at objects underneath the cursor.
The cookie jar and mug can be engaged with your weapons, soldier!
Watch out for the huge insect creatures. Intelligence reports indicate that these things are extremely dangerous and ugly.
The portal must be hidden in some sort of container.
Look carefully and get your men out of there!
Map 2 - Homeland (06:08)
1. Retake radio installation.
2. Find the wrench and fix the radio transmitter
3. Go to the train platform and jump on the train.
Briefing for Map 2:
Sometimes you just have to stand your ground and fire into the tan of their eyes.
Crouching behind rocks or other objects will decrease your chances of getting hit by enemy fire.
Tactical positioning on higher elevations will make it hard for the enemy to hit you.
Things are not always what they seem.
You have to make sure the train can make it out of there!
Map 3 - Tank Store (23:14)
1. Eliminate the threat from the Tan saboteurs and report it back to headquarters at the Tank Factory.
2. Defend the train from Tan armor units.
Briefing for Map 3:
The radar will allow to see any approaching enemy that are in range on your strategic map.
The train bridge and the train tunnel are vital to the Colonel's mission.
You can use the Vehicle Repair Facility to fix damaged vehicles.
The Train is vulnerable to tank fire.
Map 4 - Airbrone (31:31)
1. Secure Maynard Airfield
2. Rescue the Blue Spy from the tan soldiers.
3. Escort the Blue Spy and the Old Man to the helipad. They must be protected at all costs.
Briefing for Map 4:
Use Recon power-ups to keep an eye on enemy movement.
The Blue Spy was last seen somewhere south of Airfield
Blue Spies have a natural ability to blend in with their surroundings.
Radar stations are also excellent for keeping an eye on the enemy.
The Tan Army will know when they have lost the airfield. Expect them to send in reinforcements.
Rapid execution is the key to success in this mission, solider.
