That 76mm gun on the Dodge M37 looks like a Yugoslav 76mm M48 mountain gun
I’ve been looking at a whole heap of old Indonesian Archive images from this Facebook Page: Priyono Bitles Combat | Facebook. There are some interesting images of Indonesian vehicles (some I didn’t even know we used) as well as other interesting & rare images of historical events and the like (ships, aircrafts, infantry, etc.). I’d suggest taking a look if you’re interested in that sort of stuff
What i found from there was that for the new light tank procurement program in around 1983, two wildly different designs was tested, but ultimately went with the marked-up Alvis Scorpions due to “reasons”.
Vehicles Tested
The first is the Wiesel which we already know was tested with the .50 cal turret, but apparently it was also tested the 20mm variant as well
Wiesel
The second design we tested was the Austrian SK-105 Kürassier, honestly I have no clue about the variant differences, but since they’re firing at night I would assume it has thermals or NVD
Although we didnt buy either of them, the SK105 turret was eventually used in the amx 13 retrofit (yonkav 2)
with that out of the way here are some additional rare images of tanks/vehicles we used

With the appearance of multi vehicle SPAA, we could expand the tree to include the SPYDER MR from the Philippines and/or the MBDA SAMP/T from Singapore. Although I wonder, does anyone know any updates on Indonesia acquiring their own version of the HISAR-O?
Edit:
Missed another part of the update that adds the SPYDER AIO, now it would be even more easier for Gaijin to add the SR and MR versions!
They were ordered on 2022 but no recent news, supposed to be the Trisula-O (Medium-Range) & Trisula-U (Long-Range) as well as the SİPER
it would be similar to this
but with the Czech Tatra truck (currently unknown which version, could be this)

plus technically it wont be the multivehicle system we can add since we have NASAMS, Rapier, Skyshield,
GROM Poprad w/ Cobra ADS, etc
NASAMS, Skyshield, and Rapier (I suppose Rapier could be considered but wouldnt really be a match for the SPYDER systems) technically arent vehicle mounted and would be stretching the definition of vehicle based combat of WT. Also dunno how would the entire Grom Poprad Aster system would be employed, like there would be technically 2 different weapons configured to a search radar. Now if only the Badak Skyshield was real tho
its how its currently implemented though, with one radar-less vehicle as the weapon system and another as the radar (except at a lower BR obviously)
