get yourself a dozer, preferably a D11, a lot of armor plates, a good industrial grade welder, a ton of welding sticks/wire/filler rod depending on which welder you use, remember TIG is best
you will stomp right in with that thing, literally unstoppable unless you run out of fuel, once you’re in make sure to get everything these cunts stole from us intact, probably a few gold bars too if possible but that’s a side mission already
now in all seriousness, a similar kinda thing has happened already with someone beefing the fck out of a dozer and going on a revenge rampage
