Thanks for all your help guys, genuinely informative and has helped me playing the game no end. As stated, the last time I played the game was 1996 so you'll have to forgive me if my memory is a little 'foggy'
So again, thank you for all your help, it's very much appreciated ;-)
(We can all joke x)
Genuinely enjoying playing the game again, and yes, I now remember you can't put troops in the pillboxes. Thank you
