Bulldozers employed for [[Combat engineer|combat-engineering roles]] are often fitted with [[armor]] to protect the driver from firearms and debris, enabling bulldozers to operate in combat zones. The most widely documented use is the [[Israel Defense Forces|Israeli Military]] militarized [[IDF Caterpillar D9|Caterpillar D9]], for earth moving, clearing terrain obstacles, opening routes, and detonating explosive charges. The IDF used armoured bulldozers extensively during [[2004 Israeli operation in Rafah|Operation Rainbow]] where they were used to uproot [[Gaza Strip smuggling tunnels]] and destroy residential neighbourhoods, water wells and pipes, and agricultural land<ref>{{Cite news|date=2012-08-28|title=Profile: Rachel Corrie|language=en-GB|work=BBC News|url=https://www.bbc.com/news/world-middle-east-19395651|access-date=2021-07-22}}</ref><ref name=":1">{{Cite web|date=October 2004|title=Razing Rafah: Mass Home Demolitions in the Gaza Strip|url=https://hrw.org/reports/2004/rafah1004/rafah1004text.pdf|access-date=2021-07-22|archive-url=https://web.archive.org/web/20060324184921/https://hrw.org/reports/2004/rafah1004/rafah1004text.pdf|archive-date=2006-03-24}}</ref> to expand the military [[buffer zone]] along the [[Philadelphi Route]].<ref name=":1" /> This use drew criticism against both the use and the suppliers of armoured bulldozers from human-rights organizations such as the EWASH-coalition and [[Human Rights Watch]],<ref>{{Cite web|date=2004-11-21|title=Israel: Caterpillar Should Suspend Bulldozer Sales|url=https://www.hrw.org/news/2004/11/21/israel-caterpillar-should-suspend-bulldozer-sales|access-date=2021-07-22|website=Human Rights Watch|language=en}}</ref><ref>{{Cite web|title=Israel's violations of human rights regarding water and sanitation in the OPT - Report by Al-Haq and EWASH to CESCR - Non-Un document|url=https://www.un.org/unispal/document/auto-insert-195880/|access-date=2021-07-22|website=Question of Palestine|language=en-US}}</ref> the latter of whom urged [[Caterpillar Inc.|Caterpillar]] to cease their sale of bulldozers to the IDF.

Some forces' engineer doctrines differentiate between a low-mobility armoured dozer (LMAD) and a high-mobility armoured dozer (HMAD). The LMAD is dependent on a flatbed to move it to its employment site, whereas the HMAD has a more robust engine and drive system designed to give it road mobility with a moderate range and speed. HMADs, however, normally lack the full cross-country mobility characteristics of a dozer blade-equipped tank or armoured personnel carrier.

Some bulldozers have been fitted with armor by civilian operators to prevent bystanders or police from interfering with the work performed by the bulldozer, as in the case of [[Strike action|strikes]] or demolition of [[Eminent domain|condemned]] buildings. This has also been done by civilians with a dispute with the authorities, such as [[Marvin Heemeyer]], who outfitted his Komatsu D355A bulldozer with homemade composite armor to then demolish government buildings.

=== Remote-controlled dozers ===
In recent years, innovations in the construction technology have made remote-controlled bulldozers a reality. Now, heavy machinery can be controlled from up to 1,000 feet away. This contributes to the safety of workers on the jobsite, keeping them at a secure distance from potentially dangerous jobs.

The advancement and the ability to control the heavy machinery from afar provides workers with the sufficient control over the dozers to get the job done. Though these machines are still in their early stages, many construction companies are using them successfully.{{citation needed|date=August 2020}}
