When, a few weeks ago I found myself in need of an AT missile platoon for my 1970s 'French' mechanised infantry regiment (despite the name this is a battalion sized formation) it was obvious that some fast bodging was required. Some basic research revealed that prior to adoption of Milan the standard light AT missile was ENTAC - some jeep mounted (now there's a bodge for another day...) and some on portable ground mounts.
A quick rummage in the spares box yielded a couple of 1/72 Sparrow air to air missiles which were soon chopped down to around the right size. The other bits of Sparrow will produce other AT missiles in the fullness of time. The mounts are 1/72 ammo boxes with parts of the rails won on which the Sparrows were originally hung. So they should feel at home.
The crew figures are from the same batch of nasty plastic army men as the rest of the regiment only with their rifles carved away. However numerous it's flaws this is clearly an infantry AT unit - and that's good enough for me. And very much in keeping with the principles - such as they are - of the Little Cold Wars project.
