So I was wondering if each factions vehicles are different stat wise. Cause the other day, I read that each factions vehicles differ in appearance and stats. Is that true? If so, what are the stats of each factions vehicles? If not, is each factions vehicles just different in appearance.

Thanks.

I don't think so

The jeeps, the APCs and the tanks have different stats (speed, acceleration, dmg, HP, capacity, rotation speed, etc.).
It would just need to be added in the wiki by anyone from the community

If I can figure out the different stats for each factions vehicles I would add it to the wiki. I'll try to figure it out if I can. Thanks Jack!

Just look at the .vehicle files in .../RunningWithRifles/media/packages/vanilla/vehicles/...

The lines that matter should be 8 & 10, starting with control (max speed/handling/etc.) and physics (health/mass/etc.).

The vehicles page table will probably need modifying to support more columns for the new values, along with new images.

also the weapon file should be investigated as you might also have different rotation speed values of the turret, different retrigger times and projectile dmg in the specific *.projectile file.

Rotation rates appear to be defined by the vehicle (lines 15 & 16) but there's definitely some variance in weapon damage, blast radius, etc. looking at the weapon/projectile files.
