I was test driving the PUMA because I wanted to see what it was like to use and I saw an M109 parked somewhat randomly. I thought it was a little weird or something I missed in the past but it’s not there for any other tank that I know of.
It’s to test the active protection system, there’s a circle, like a mini capture zone, that you drive into and it will give you a pop-up/warning that you’re about to get shot at, the m109 is what does the shooting, which is why it’s there, I believe.
It’s for aps testing you can also bring tanks like t80um2 or Black night so u can see those aps destroying that missiles when u stand in the white circle right of your spawn
