Type 76 spaa from thailand.
Originally it was british vickers company design for ammunition carrying and artillery pieces.
Thais added british 40 mm pom pom autocannon.
Can be event squad or standart unlockable after the merge.
Under same category with ta se
I think first unlock and analog against m13 should have been type 98 20 mm or type 76
Both were extensively used during war and have better firepower than ta se, better at infantry shooting etc…
adding ta-se as first unlock was unblieveable wrong decision
So you are probably asking “why japaness should able to use a thai weapon”
Well
Brits can use garands as primary semi autos altough is was not standart issued weapon
Or us soldier can use british smles
Or german can use italian hungarian romanian weapns etc…
Why not axis forces at asia couldnt use some pf their weapons interchangibly
(Yes thailand was ally with japan)
I also want to see siamese mauser one day.
