Bulldozer's armor is a fictional item featured in comic books published by Marvel Comics. A variation of the armor first appeared in Defenders #17 in November, 1974.
The armor is utilized by Henry Camp during his career as the super-villain Bulldozer. It is not a full body armor, but rather an apparatus comprised of various components including a chest plate, a helmet and a neck brace. This armor helped to fortify Bulldozer's already impressive enhanced durability, but provided additional protection and resistance to impact, which became ideal when he engaged in ramming attacks. The helmet was bulky however, and it did decrease his peripheral vision, which ultimately would leave him vulnerable to attack.
After Henry Camp seemingly died, his daughter, Marci Camp, took up the mantle of Bulldozer. She wore an armored shoulder harness and helmet similar to the one once worn by her father. It appears to have offered the same level of protection, but did restrict her visual perception as well.
