Achilles' Tracks

Historical Background

After studying the German Blitzkrieg of 1939-1941, the US Army incorporated the idea of tank destroyers - fast, lightly armoured vehicles with high velocity anti-tank guns to deal with the armoured spearheads of the blitzkrieg. The result was the M10 Gun Motor Carriage based on the M4 Sherman tank but with thinner armour in order to comply with the high speed requirement. At the same time the British were examining the design for a low-silhouette tank destroyer with a 360-degree rotating turret mounting the hard-hitting Ordnance QF 17-pounder gun with armour able to resist 50 mm rounds at 800 yards. However, with the British resources and industry working at full capacity, together with the availability of Lend-Lease, the project was cancelled and they received the M10, nicknamed Wolverine in British service. The British received their first Wolverines in 1943 and found the M1 3-in anti-tank gun arming them gave better performance than the Ordnance QF 6-pounder anti-tank gun and equal to the 7.5-cm KwK 40 gun arming the Panzer IV and Sturmgeschutz III.

The British however still wanted to mount the 17-pounder gun but the main problem is how to mount the gun onto the existing vehicles. However, the initial batches of the British M10 had an easily modified mounting to facilitate the replacement of the M7 gun with the newer M1. The mounting also allowed the British to eventually mount the 17-pounder gun. But for later batches of M10s, only the T71 type can be converted while the T70 can only mount the lighter M1. The M10-based conversions were nicknamed Achilles Ic while M10A1-based conversions were called Achilles IIc. The 17-pounder was able to penetrate 131 mm of armour at 1,000 meters at 30 degree angle of penetration using APCBC rounds. The limited-availability APDS round can penetrate 192 mm at the same range and angle of attack. By comparison, the same APCBC rounds fired from the American 3-in gun can only penetrate 88 mm of armour while the very limited HVAP round can only penetrate 127 mm of armour. All these numbers show the clear superiority of the 17-pounder gun. Because of its length, the 17-pounder gun of the Achilles was fitted with a counterweight, giving it a distinctive appearance compared to the M10.

In practice, the British used the Achilles as a mobile anti-tank gun, able to reinforce an infantry attack and engage counterattacking enemy forces, while waiting for the slower towed 17-pounders be brought into position. This was actually in line with the original American concept of the tank destroyer. The Achilles was usually used in an offensive manner in support of Churchill tank-equipped units, which was not supported by the Sherman Firefly or the Challenger tank. The Achilles equipped the units of the Royal Artillery and Royal Canadian Artillery in Armoured Divisions or Corps Anti-Tank Regiments. The most successful action taken by the Achilles was during Operation Charnwood, when Achilleses and towed 17-pounders of the 245th Battery, 62nd Anti-Tank Regiment of the Royal Artillery stopped an attack by a mixed force of Panzer IV and Panther tanks of the 12th SS-Panzer Division Hitlerjugend, destroying thirteen panzers while losing four of their number.

The British received 1,650 M10s during the war, of which 1,100 were converted into Achilles standard. It was planned that 1,000 would be converted in time for Operation Overlord but eventually only 124 had been converted by 6 June 1944. Losses among Achilles-equipped unit at the time meant that replacements were often regular M10s, much to the crews' dismay. The numbers however picked up by the end of 1944 finally reaching the figure stated beforehand. 

The Kit

Two years after the release of the M10, AFV Club released the 'Anglified' version - the Achilles. The majority of the parts in this kit are the same with the ones in the M10 kit. The Achilles kit added a new sprue containing British-specific parts such as the gun mantlet, British-style fire extinguishers, British No.19 radio, spare track-link mounts, three Sten Guns with alternate metal stocks and six 17-pounder rounds for the ready-round racks. A new turned aluminium barrel is also included. Decals provide markings for six vehicles:

1. 93rd Anti-Tank Regiment, Royal Artillery, 5 Corps Italy 1944

2. 1st Army Corps, Normandy 1944

3. 75th Anti-Tank Regiment, Royal Artillery, 11th Armoured Division, Belgium 1944-45

4. 4th Anti-Tank Regiment, Royal Canadian Artillery, Netherlands 1945

5. 21st Anti-Tank Regiment, Royal Artillery, Guards Armoured Division, Netherlands 1944

6. 1st Anti-Tank Regiment, 1st Polish Armoured Division, Netherlands 1944

While other reviewers didn't mention it,  the decals in my kit were badly printed, with the Guards Armoured Division insignia and all of the arms of service insignias out of register. 

Construction

Since the Achilles, like the original M10 is an open-topped vehicle, construction started at the interior. Not much however is included (and as I have never seen the actual interior, it's rather moot actually). What were there however was nicely detailed. There are seats for the driver and his assistant but no control columns were included. The instrument panel was painted and drybrushed (although I shouldn't bother, really). The ammo rack on the sponson is there but unlike the M10, rounds were not provided. The beautifully-detailed transmission were next. After assembly, it was cemented to the transmission cover and the whole thing was mated to the main hull. The interior then received a rather heavy dark wash. Moving on to the suspension, AFV Club's VVSS suspension has a bit more breakdown than other companies' allowing more articulation especially for dioramas (which I don't need). It was quite tedious but strangely enough, after all the effort making the suspension articulate, they have the wheels with hollow backs.....The rear plate and all the fittings was then fitted to the hull, although I left the exhaust for the time being.

Before doing anything else to the upper hull, the faint raised circles marking the locations of the applique armour bosses were sanded off (unless you're doing the Canadian version).  Like the M10 kit, the driver and co-driver's hatches can be made moveable but I also decided to cement them shut as there were no sitting figures to fit there nor there were interior to speak of. The rear plate was then cemented but the tools placed there were left off until after painting has been done. The fit was was quite bad and needed putty to fill the gap. It should be noted that there is a difference for the location of the tools between the Canadian version and the rest of the options in the kit The grouser rack were then cemented to the hull. Again the location is different on the Canadian option. At the front of the hull, AFV Club gave options for the placement of the radio aerial and the right-hand side light (either on the same location as on the M10 or on the front plate for the former and either on the edge of the front plate or on top of the right headlight for the latter). The empty ammo racks on the sponson were partially filled with ammo from Bronco - just to have something in it.

On to the turret then. The turret is basically a carry-over from the M10 kit. However the upper rear panel is a straight piece of plastic which need to be folded to fit on the lower half (fit is a bit of a misnomer here). Also, instead of generic ammunition style (or using ammo from the M10), AFV Club provided 'proper' 17 pounder ammunition for the turret ready racks. I did not use them however. Instead I used the even better items from Bronco. They are however larger than the kit ammo but fortunately, they fit into the kit ammo racks (except for the topmost, right-side rack). A Sten Gun with alternative butts was also provided. The instructions have the magazine in place but I don't think the gun was stowed as such, so the magazines were left off. The real difference of the turret is at the front with a different mantlet and the gun (of course) and the differently-shaped counterweights on the rear of the turret. The M2 heavy machine gun was left off the this time to ease handling of the turret. And, to ease painting (more or less) the interior parts were painted before they were assembled, with touching-up of the paint took place after construction.

Painting and Decalling

Allied vehicles are pretty straightforward to paint by (usually) having just one colour. In the interest of accuracy, the Achilles should be painted SCC15 (British) Olive Drab. Since I usually paint using Tamiya stuff and Tamiya does not have this colour, they need to mixed using Tamiya paints. I However ran out of some of the paint, and so I painted it 'straight' XF-62 Olive Drab. The majority of marking options in the kit have plain schemes and to add a bit more variety to my collection, I decided to finish my model in the Guards Armoured Division markings. The camouflage pattern was painted using Tamiya XF-69 NATO Black. The decals were applied next. They settled without any problems but you can't help noticing the rather obvious mis-register (is there such a word?) of the decals especially the arms of service marking. The model then received a wash using stuff from AK Interactive.

Finishing

I didn't mention it early on but the tracks were fitted onto the running gear before the upper hull was cemented to the lower half. The tracks were painted XF-64 Red Brown as base while the track pads were painted XF-69 NATO Black. It was earlier decided that turret opening is wide enough for some parts to be left off and so only at this time the ammo pieces were put in place, together with the aforementioned Sten. AFV Club did not include stowage so I added some from my stash and from Bronco's 17-Pounder Ammunition Set and British Field Accessories Set. The turret and upper hull received a thin layer of XF-57 Buff to stimulate dust. The Buff layer for the hulls was streaked down to simulate rain marks. The marks were enhanced here and there using AK Interactive Weathering Pencil. The lower hull received mud applications using Vallejo Splash Mud, Ammo Dark Mud and AK Interactive Earth Effects. 

Conclusion

While the amount of detail is pretty good for the outside, I believe that interior is simplified and is something that is not so good for an open-topped vehicle. The fit is also not very good especially for the turret walls and the rear hull plate which require putty. The decals is one of the worst for a mainstream kit with out-of-register printings. And, apparently, like their M10 kit, the turret is rather inaccurate although I don't have any means to verify the claim. Anyway it does look like an Achilles's turret so there. It is nevertheless a very buildable kit and recommended to all. Of course, if you want to have an easier build, there' always the newer Tamiya kit of the same vehicle!
