Scout vehicle with Adante Mk3 Bazookas on a twin mounting. Perfect for stalking enemy armour.
This model was from my childhood years in the early 1990s - back when the only guns available were brown muskets, and green and brown Lego bricks were very rare. Even light grey was not a common colour (no dark grey or tan for ordinary bricks either). No real decent minifigs then either to do soldiers - thus my lot were always a citizen militia.
The concept of that vehicle is sound; small, fast and can launch two ATGMs then run before being spotted and targetted. Many such vehicles exist in real life - the Wessex Striker for example, designed to cheaply counter the numerical tank superiority of Eastern Bloc and Soviet armies in the event they ever decided to move west. The bazookas are man-portable too.
(It is still one of my favourite designs, being funtional, simple, and the colours worked nicely then)
