I have just returned to modelling after a hiatus of 43 years - 1/32nd and 1/35th scale - mainly tanks, and mainly to war-game them; and I am still in a re-learning curve. The photo-etching was new to me, and I have tended to ignore them when there is a normal polystyrene part option, but I used the rear grill etching on the Tamiya T-72M kit to good effect.
