In Europe, the US Army fielded only one battalion of heavy tanks, from January 1958, originally assigned to the 899th Armor, later redesignated the 2d Battalion, 33d Armor. The US Army heavy armor battalion, in contrast to other armor units, was organized into four tank companies, composed of six platoons each, of which each platoon contained three M103's, for a total of 18 tanks per company. Standard US Army armor battalions at the time had three companies per battalion, each with three five-tank platoons, with 17 tanks per company (two tanks were in headquarters platoon). The US Marine Corps assigned one M103 company to each of its 3 Marine tank battalions, including its Marine reserve units. The M103 was never used in combat.

While the US Army deactivated its heavy armor units with the reception of the new M60 series main battle tanks in 1963, the remaining M103s stayed within the US Marine Corps inventory until they began receiving the M60 series main battle tank. With the disappearance of the heavy tank from US forces came the full acceptance of the main battle tank in 1960 for the US Army, and 1973 for the US Marine Corps. Although the 21st century's M1 Abrams main battle tank utilizes the same caliber of main gun, 120mm, the M103's cannon was a rifled gun firing a separate-loading round, in which the projectile was loaded into the breech, followed by a cartridge case consisting of a brass case, primer, and propellant in a fixed unit. This separate-loading system necessitated the use of two loaders. The only part of the cartridge case consumed during firing was the propellant and a plastic cap on the end of the brass cartridge case. The spent brass cartridege case was ejected after firing. The M1 tank's 120mm main gun is a smooth bore firing a semi-caseless round, ejecting only a back cap of the original loaded round; the bulk of the M1's 120mm shell casing is consumed during firing. 

Those who like 1/72 armor have been awaiting this one since the 1/35 version was released nearly two years ago. One nice thing about Dragon is that they will produce many of the 1/35 kits in 1/72 scale, though it may well take a little time for that to happen. No sense letting all that CAD work go to waste!

The result of this is a kit that pretty much defines 'weekend edition'. There are four sprues in grey plastic and a definite dearth of the usual mass of fiddly bits we have all come to expect from Dragon. What few there are, Dragon has put on the turret with a few on the forward hull.

The suspension on each side is a single gang mold. Tracks include molded on return rollers, idler, and road wheels. Only the sprocket is separate. Each side consists of an inner and outer construct that when put together, form a natural seam down the middle of the track links. Though the instructions do not actually show you gluing the upper and lower hull pieces, that is, in fact, what you will do at the start of the build.

There is a full upper turret onto which the various baskets, hand holds vents and the 50 cal machine gun are located. The barrel slides through the mantlet and this is then trapped between upper and lower turret pieces. I imagine that most will glue this in place as that is a lot of plastic to be held up in the air. That's it. At a parts count of 40, it will tax few.

Instructions are simple compared to previous 1/72 armor kits in that there isn't the usual slick paper and color. With all three options being in OD and based in Germany during the late 1950s, there really isn't any need. These are, by the way, the same markings options as provided in the 1/35 kit. Decals are nicely done, all with a tad bit of color in them to help break up all that OD.

CONCLUSIONS

Quite a few modelers have been waiting for this one and now it is here. Probably the most difficult part of the build will be painting the road wheels and return rollers, so break out the 5/0 brush and magnifiers for this one! Also, if you want a canvas covering on the mantlet, you'll have to make it as it is not included. As a side note, I'm often puzzled as to why this feature is rarely molded on US tank kits as it seems they all had it at one time or another.
