From the website:
Napoleonic French Engineers were men charged with building bridges and fortifications as well as breaking down the gates and obstacles protecting the enemy. As such they were amongst the strongest men in the French army.
These characterful models are provided with an option to build them with the Charleville musket or with an engineer tool such as logging axe, spade, billhook, etc. This allows for a great deal of flexibility in the way you field them on the tabletop. Either way, they are getting stuck in!
