Another great Squad falls. RIP
Happy birthday!
ps. removed an offensive post above

We do not currently accept vehicle mod suggestions as these are instead polled by the clan, but if you've got one that you think holds a lot of potentials you're welcome to message me. On the other hand, we do accept vehicle handling suggestions.
