Those Aussies do look good!
Where’s the upper track run on that bucket? Hoping empress will treat us with both T50 turrets and M74C turrets for the Australian buckets. The M74C version covered much of 1967-68 including, I believe, the Ba Ria and Binh Ba engagements. If it came as an extra, item that could be swapped for other turret options it would be great. The Aussie M113 also needs a new cargo hatch. Australian versions had a boxy ventilation system mounted on the hatch.
