Plus the speeders and bikers I've done which are another one hundred and one marines that makes a grand total of eight hundred and ninety three painted marines.

11 infantry scouts
20 scout bikers
10 devastator centurions
4 assault centurions
9 tactical sergeants
2 tactical marines with heavy weapons
36 tactical marines
5 honour guard
5 x 5 man command squads
