India in ‘71 gets T-54 as well, in fact they are the main MBT in use by then. As Pakistan had near identical T-59s, the Indian army put fake, sheet metal fume extractors mid way down the barrel for recognition purposes.
IIRC the Shermans were not Easy 8s, they were re-gunned earlier models, in Pakistan’s case renovated older Shermans supplied under MAP, mostly ex M4A1 hulls. US supplied a lot of these M4s post war as aid, see the Yugoslav Shermans in Kelly’s Heroes as an example. The E4 version applies to rearmed A1 models, E6 to former M4A3s. They also had a number of ex Indian Army Shermans from partition, possibly M4A2 or M4A4s. Don’t think the Pakistanis used M4s at Asal Uttar, just Pattons and Chaffees but I may be wrong.
The Indian ones were domestically re-gunned M4A4 and A3s. They also converted a couple of regiments’ worth with French 75mm guns, rather like the Israelis. India also still had 75mm armed Shermans in 1965.
Otherwise looks pretty good, although the majority of photos show both sides wearing the old British battle bowler on both sides, at least in 1965. Pakitan seems to have had a mix of SMLEs and M 1 Garands in 1965 and the Indians were definitely using SLRs, with second line troops maybe still having SMLEs. By 71, Pakistan has an eclectic mix for its frontline troops of G3s and AK clones.
