In Battlefield 1, the Assault Class is an anti-vehicle class which has mines, AT Grenades, Rocket Guns, Dynamites and other tools which are very useful for a tank hunter. First, you need to grab the tool which you know you are best with. Like for example, Dynamites, where you need to judge the tank’s movement before you throw or attack it.
Note: Always take cover and keep moving in and out to avoid the return fire. Next, you can try are the AT Mines which should always be placed in the area that leads to the Capture point. This will not only slow them down but also drains the nearby enemies health. Lastly, you can use the AT Rocket Gun to aim and destroy the mini tanks or half damaged tanks. Hint: If you have a Pilot in touch then, coordinate with them and ask them to help you with backup.
