Construction notes for M48A5K from Academy, may be built as Korean or US version of the M48A5 by Lance Mertz:

If you have built any Patton tanks this kit should hold no real surprises for you.  The only question you have is which version to build.  I chose the Korean version, as it allowed for more interesting changes.
The M48A5 is pretty much an M48 with a 105MM gun, except for a few turret details.  The Korean version adds a few twists to this. 

The chassis is a standard M48 chassis and goes together just fine.  The only change are the side skirts, which the Koreans have added to increase protection from anti-tank missiles and HEAT rounds.  They definitely make the tank distinctive.  They go on easily and fit perfectly.  I replaced the headlights with a set of Greif M60 lights and they look great.  This was my first use of Testors Clear Part cement and I was impressed with it. 

I used an aluminum barrel for the gun, which definitely is a plus, though the one that comes with the kit looks fine.  I also used an Minimica Antenna.  The construction was straight forward until I got to the wiring for the smoke grenade launchers.  You need to provide your own wire for this and I have a spool of think black wire.  The kit come with brackets to hold the wire down.  These wire run from a fitting on the top of the turret to the smoke grenade launchers.  It is not difficult to accomplish.  The cable for the searchlight comes with the kit and is very nice.  I have enough left for at least one more tank.   

Painting was done in three stages, including some repainting.  I primed the tank with Testors Gray Primer, which gives you a nice starting point.  Then I used some light green and tan spray only Testors paints I have, airbrushing a random pattern on.  My blacks simply refused to spray properly, making a mess!  I over painted much of the black and brush-painted on Choas-Black, which is a nice, dark color.  This was too dark and the green too green, so covered the entire tank with an Umber wash, which toned down both, giving is a slightly weathered look.  I also did the same with the tracks, which I used from the kit.   

The machine guns that come with the kit are nice, as are most of the smaller parts. 
The kit comes with a couple of figures, but I had purchased the Academy Korean Tank crew, so I assembled and painted the figures according to the box art.  They are well molded and come with lots of nice weapons and accessories.  I put some ammo boxes and other stuff in the bustle rack, too.

The decals were very limited, but the ones provided worked fine. 

Overall this was a very nice kit to build and I recommend it to anyone tired of the standard fare.
