In September 1939 Poland had engineers and pioneers embedded with the regimental and brigade structures of the army theoretically allowing all forces to have elements at their disposal that would facilitate in the parental organisations manoeuvrability as well as being able to clear mine fields or destroy enemy hard points.
With the habitual headlong retreat that Polish forces suffered in 1939 it was a rare event that Polish engineers were able to play to their strengths at anything other than destroying bridges and frustrating Nazi advances.
There are no miniature manufactures in the world that produce Polish Engineer miniatures in 15mm so I had to cast my eyes about for a workable parallels.
Firstly was the issue of finding their transport vehicles. The Czech Praga RV six wheeled trucks. After much searching I managed to find a single manufacturer of these trucks and that was QRF Miniatures in their German range.
The trucks needed an enormous amount of cleanup and nothing seemed to fit together properly BUT once the paint jobs were applied they passed muster!
The other miniature in the US Army Sappers, Pioneers and Engineers pack that can easily be shoe horned into your Piechoty force is the sapper that is carrying the satchel charge. With the same trimming to the helmet as then mine detector got he becomes easily the most passable version of a US solder in Polish service!
