A wood-planked, L-shaped mantlet on wheels. Wooden-planked construction with proper joinery and even arrow slots would make this a more hard-wearing and expensive option. It would be heavier to push and would require more time and skill to construct; this might not be the sort one would use when attacking uphill.
A pavise (free standing shield) like wicker mantlet. This is probably the cheapest and simplest option, but it would not be as hard wearing and does not offer as much cover as the other variations.
The Japanese commonly used mantlets composed of bundles of blankets wrapped in a mattress to reduce the effects of shell shrapnel. Print of Admiral Togo aboard the Mikasa during the Battle of Tsushima (May 27, 1905).
In military use from pre-WW2 onward, a mantlet is the thick, protective steel frontal shield, usually able to elevate and depress, which houses the main gun on an armoured tank, examples being Tiger Tank, Sherman Tank and Churchill Tank .
