The Imperial Gaurd was equipped with 80mm mortars.
One mortar crew consisting of a mortar and a crew of three, as shown.
The mortar has a bar on the bottom that connects the two legs of the bipod. This was added for casting and can be removed–but it also can be left on to help embed the legs in the groundwork of your basing.
NOTE: All figures are sold plain (not primed or painted) and without additional basing.
