Tank Destroyer 'Achilles' M10

The Achilles IIC: Key Features

Feature	Description
Original Base	The American M10 Tank Destroyer (specifically the late-production M10 II variant).
Main Armament	The British Ordnance QF 17-pounder gun (76.2 mm), one of the most powerful and effective Allied anti-tank guns of the war.
Designation	The official designation was 17 pounder, Self-Propelled, Achilles. The ‘Ic’ and ‘IIc’ nomenclature denoted the type of M10 chassis used, with the ‘c’ signifying a vehicle equipped with the 17-pounder gun. The Achilles IIC was a conversion of the diesel-engined M10 II (M4A2 chassis).
Role	Tank Destroyer. Its high-velocity 17-pounder gun was specifically intended to knock out the heavily armored German tanks, like the Tiger and Panther, which the standard American 75 mm and British 75 mm guns struggled against.
Armor	Light and Sloped. Following American Tank Destroyer doctrine, the armor was relatively thin (ranging from 9 mm to 57 mm), prioritizing speed and gun power over heavy protection. The turret was open-topped, a design choice to save weight and improve crew visibility, though this made the crew vulnerable to artillery, mortars, and infantry fire.
Combat Effectiveness	Excellent Firepower. The 17-pounder, especially when firing APCBC (Armour-Piercing, Capped, Ballistic-Capped) or the potent but scarce APDS (Armour-Piercing Discarding Sabot) rounds, gave the Achilles the hitting power necessary to deal with any German tank it encountered.

Conversion and Service

The Need: By 1943, Allied forces realized their primary tank armament was being outperformed by the armor on new German tanks. The British had developed the superb 17-pounder gun, but needed a mobile platform to mount it.
The Solution: The American-built M10 was available via Lend-Lease, and its turret ring was large enough to accommodate the massive 17-pounder. The British Royal Arsenal, Woolwich, carried out the conversion.
Modifications:
- The American 3-inch gun was replaced with the longer, heavier 17-pounder.
- A large, distinctive counterweight was added to the rear of the open-topped turret to balance the weight of the new, heavier gun.
- In some cases, applique armor plates were added to the hull and turret sides for slightly better protection.
In Battle: The Achilles IIC served with distinction, particularly in the later stages of the war in North-West Europe following the D-Day landings in June 1944, and also in the Italian Campaign. It was often deployed in anti-tank regiments of Armoured Divisions or Corps formations.

The Achilles IIC, often simply referred to as the “17pdr M10,” was, after the Sherman Firefly, the second most numerous armored fighting vehicle to carry the decisive 17-pounder gun, with around 1,100 units converted.
