Heres a suggestion.
Warboss,
MA, attack squig, da Stikk, Bosspole (He joins one of the boyz mobz and tanks wounds for them).
3 Meganobz, Trukk with Ram & rokkit (These guys will flank you opponent)
30 boyz slugga/choppa, bossnob with pole and klaw
30 boyz slugga/choppa, bossnob with pole and klaw. Trukk with rokkit. (Trukk is for the tankbustas, but bought as a troop choice it gains Objective secured).
5 tankbustas (steal the boyz trukk and goes where they are needed)
5 Mek gunz, 10 additional grot crew, 5 ammorunts (I have used kannons instead of smashas, because kannons are cheap as chips and hard on marines)
An even 1000 points battleforged army.
Tactics.
Well it depends a little on what and how your opponent usually plays, but if he uses terminators, then let your
Manz hunt them down or drown them with one of your boyz mobz.
Should he be using a Land Raider (unlikely in a 1k match but not unheard of), then send your bustas in the trukk to pop it with their meltabombs (which is also the reason why you shouldnt spend points on tankhammers).
@Sick Bag: Kannons are
ID for termies as well. It's just a little harder, but that's what Orks like, innit?
