Halo themed Imp Guard army

[manrogue]

Been having a little play around and think my tank heavy imp guard list(2000 pts) may look a little like this-
HQ
Command squad w/ +1 vet, Mortar, 2xsniper, camo, master of ordance= 225
Enginseer + 3 serv= 90

Elite
6xratlings= 60

Troops
Command w/ vox, mortar= 40
Infantry squad w/ auto,Snip= 65
infantry squad w/ melta = 60
Veteran w/ 3xmelta + chimera = 155

troop 2
Command w/ vox, mortar= 40
Infantry squad w/ auto,Snip= 65
infantry squad w/ melta = 60
Veteran w/ 3xmelta + chimera = 155

Fast
Valkyrie W/ heavy bolt sponsons = 110
Banewolf =130
Tauros w/ heavy flamer(aka warthog)= 40
Tauros w/ multi laser(aka warthog)= 60

Heavy(ie the fun stuff)
Leman russ w/las, heavy bolter sponsons = 185
Exectutioner w/heavy bolter sponson = 210
2x basilisk = 250

Total = 2000
May not be massively competive, but think it would be fun to play!
