Only in recent years has the Swiss Army started to pay attention to the development of armoured and mechanised infantry units, reflecting changes in the understanding of armoured warfare within harsh terrain.
Development of Doctrine
Until recently, the Swiss Army saw almost no need for an armoured force of the type currently being refined by the armies of the Great Powers. However, Swiss observation of military exercises undertaken by European militaries convinced a number of influential observers, including Lieutenant General Ludwig Jacob, that tanks could operate in mountainous terrain long thought to be highly disadvantageous to armoured forces. General Jacob thus championed the creation of the first Swiss armoured unit in 1941.
Jacob's experimental unit was a company-sized squadron of eighteen tanks, organized in five troops: four tank troops (each with four tanks) and one command troop, with two tanks and a supply section. The tanks were fifteen-ton Renault AMC-35s on loan from the French Army - the vast majority of that type ever produced - and they served as useful exemplars for training young Swiss tank commanders, as well as developing a doctrine.
More crucial to the Swiss armoured arm, however, was their study of the League of Nations tank operations in Afghanistan. In autumn of 1941, Czech Lieutenant General Helidor Pika, second in command of the force, spoke to the Swiss Army staff college about the League's experiences in Afghanistan, where he highlighted the fluid roles that Irish and Czech armoured vehicles played in the successful execution of the campaign goals. The experience General Pika shared was at the same time causing the reworking of the Czech armoured forces. Pika's experience, and his insistence that tanks could contribute to fighting even in hostile terrain, convinced many senior Swiss commanders that it could in fact be done.
General Jacob spent much of late 1941 and early 1942 developing
Technical Instruction SP-48842, the official doctrine for the development and use of a Swiss armoured unit. Although this document is classified, it resulted in the creation of the Schützenpanzer Regiment (also known as the
Regiment Inter-Armes in French and the
Reggimento Motomeccanizzata in Italian).
Combined Arms Forces
The Schützenpanzer regiment is in fact a battalion-sized combined-arms unit, similar in many ways to the Battlegroups used in Afghanistan by the League troops. Each battalion has two mechanized infantry companies and two tank companies, for a total of thirty-six tanks. A regimental train, an artillery company with six self-propelled guns and nine mortar carriers, a headquarters company and a reconnaissance company round out the Schützenpanzer Regiment.
Compared with the armoured divisions fielded by most of the first-rank nations, the Schützenpanzer Regiment is small, lacking in sheer overwhelming firepower. But in the Alps, neither the Swiss nor any potential attacker would be able to find the necessary room to employ such massive units. The sheer size of an armoured division plays against it in restricted terrain. The Swiss have sensibly chosen to keep their tank units integrated with the infantry on a much lower level than is usual in Europe. The Schützenpanzer units thus incorporate at the battalion level all of the major elements of a modern army: armour, infantry, artillery, reconnaissance, and combat support. This microcosm of mixed forces is perfectly sized for operations in rough and constricted terrain, where the units possess a more intimate working relationship. Although it lacks staying power in a large fight, the Regiment's small size allows it to react quickly to developments, either on the attack or the defense.
In order to accomplish this closer pairing of infantry and armour, the Swiss followed the lead of other nations in outfitting the two rifle companies with armoured carriers. However, this is where the similarity ends. Unusually, the Swiss chose to procure fully-tracked infantry carriers for use by their infantry, whereas most nations use a more economical half-track or wheeled truck conversion. This allows the infantry the surety of supporting the tanks in whatever terrain they should find themselves.
Experimentation by General Jacob's test units, as well as studies composed in France, Germany, and elsewhere, has proven that combined operations between infantry and armour are the keys to successful utilization of armoured units in closed terrain. In open terrain - for instance, the European plains or the North African desert - armour may lead the way, with infantry moving in close support. The tanks, with their mobility and long-range guns, become the dominating force of the battlefield - but this does not reduce the need for infantry to come up in support. In closed terrain, this calculus must change. The infantry must lead, while the tanks follow in support. This follows the general methodology used by the League forces in Afghanistan - although it does not prevent the on-scene commander from exercising his prerogative to change tactics. In both cases, adherence to one methodology or the other may be fatal: cooperation and flexibility by combined arms units is demanded.
Materiel Component
The first Swiss tanks were retired AMC-35s leased from France, but it soon became clear that these vehicles were both insufficient for Swiss requirements (lacking mobility and potency) and already well-aged. Through 1942 and early 1943, the Swiss sought out tank designs for evaluation. Development of an indigenous Swiss tank was considered, but rejected; the Swiss evaluators determined that the country lacked sufficient design experience to build their own tank, and estimated that a homemade design would not be able to benefit from sufficient economies of scale to be financially sound. However, the greater number of required armoured carriers made this a possible field for Swiss innovation. Thus, the Swiss adopted a two-pronged approach.
First, in late 1942 the Swiss acquired a set of used Czech LT.38 light tanks, which they converted at the Swiss Federal Constructions Works (EFW) into prototype armoured infantry carriers, dubbed the Schützenpanzer 42. A license for local production of the basic LT.38 chassis was shortly acquired, and the new vehicle, dubbed the Schützenpanzer 43, is now being manufactured by EFW, with an initial order for two hundred and sixty vehicles. At just under twelve tons, the SP-43 can carry a crew of two and a slimmed-down squad of eight riflemen. Once the troops are unloaded into battle, the SP-43 remains on the battlefield, providing fire support to the infantry with its 20mm gun.
In November 1943, the Swiss Army selected the Czech LT vz. 42 as the main Swiss tank, picking it over offers made by larger European firms such as Renault and Fiat/OTO. CKD/Skoda was just finishing up the LT vz. 42 production run for the Czechoslovakian Army, and they quickly transitioned into building tanks for the Swiss. These vehicles received a slightly different armament from the Czech tanks, adopting the longer-barreled 75mm/L48 M40 gun, manufactured in Yugoslavia. This potent weapon is capable of penetrating ten centimeters of armour at ranges up to a kilometer, which the Swiss believe is sufficient to deal with most of the light and medium tanks currently found in Europe.

[SIZE=1]The LT vz. 42 tank was designed in Czechoslovakia between 1939 and 1942 as the successor to the LT vz. 38 light tank and the ST vz. 39 medium tank. In April 1943, the Irish Army ordered thirty-six regular tanks and two training tanks to replace worn out Crusader cruisers. The Swiss Army ordered one hundred fifty tanks at the end of 1943 to form their new armoured branch.[/SIZE]
