FORMATIONS (TO&E), PART 9

World War II: Engineer Corps

 

During Winter War (1939 - 1940) the basic unit of Finnish Engineer Corps was Engineer Company, 33 of which were established for the Winter War. However, the sizes and organisations of Finnish Winter War era Engineer Companies varied considerably. Below are three versions, which should give some idea about the basic structure. At that time Engineers had been intended to be used as experts, which made demolitions, build minefields, build entrenchment etc, but rarely took part in combat in frontline. However, during the war also Engineer units had to often take part in battles as replacement of infantry.

Basic unit of Finnish Engineer Corps during Continuation War (1941 - 1944) was Engineer Battalion, 24 of which were established for Continuation War. Below are also TO&E of Bridge Company (9 established), Engineer Platoon of Infantry Regiment (one per regiment) and some more special Engineer units belonging to Regiment/Brigade/Division military units introduced in other TO&E pages of this website. On its own Finnish Engineer Battalion TO&E didn't officially include any flame-thrower unit before September of 1943. However unofficially Flame-thrower Platoons equipped with Italian M/40 and (soon also with) captured Soviet M/41-R flame-throwers fought in Finnish troops starting from beginning of Continuation War.

During Interim Peace (1940 - 1941) Finnish Engineer Corps sent their representative to study methods, which German "sturmpioniere" were using. These studies and Finnish experiences from Winter War lead to introduction of new training doctrine: "Taistelupioneerikoulutus" (Combat engineer training), which was spread to Finnish Engineer units during Continuation War. The combat engineer training introduced more aggressive frontline combatant role for Engineers, making its best to transform them as specialists in attacking fortifications and armoured vehicles with equipment such as satchel charges, bangalores and pole charges. September of 1943 TO&E of Engineer Battalion went through a change: The non-combatant Search Light Platoon was replaced with Jaeger Engineer Battalion armed with flame-throwers. At the same time the newly introduced Jaeger Engineer Platoons meant that the "unofficial and outside-TO&E" Flame-thrower Platoons disappeared.

 

Engineer Company, 1939 (by the book according official TO&E):

Company Commander (pistol)

Company HQ Squad

Telephone Squad

3 Engineer Platoons

Supplies Platoon

Total strength of Engineer Company: 5 officers + 31 NCO + 211 men = 247

Company had 28 towing-horses with carts or sledges. Skis were reserved for everyone for winter use. The company didn't have any automatic weapons or flame-throwers.

Notice: This by the book TO&E wasn't used when Finnish Army was mobilised for Winter War! Especially the 7 Squads strong Platoon had proved impractical already before the war.

 

Engineer Company, 1939 - 1940 (Planned, but not exactly implemented in mobilisation):

Company Commander (pistol)

Company HQ Squad

Telephone Squad

3 Engineer Platoons

Supplies Platoon

Notice: This one TO&E was planned, but it wasn't implemented (at least in large scale) either. However, it gives detailed picture of what the different parts of Engineer Company contained.

 

17th Engineer Company, 1939 - 1940 (actual real unit as an example):

Company Commander (pistol)

Company HQ

4 Engineer Platoons

Supplies Platoon

Total strength of Engineer Company: 6 officers + 27 NCO + 227 men = 260

Company had 30 towing-horses with carts or sledges. Skis were reserved for everyone for winter use. The company didn't have any automatic weapons or flame-throwers.
