Welcome to Librarium Online!
Here's a CP list that shouldn't have trouble w/the pesky Land speeders the marines always bring,but also has ways of dealing w/any horde armies.
It follows the basic strategy of letting your infantry be anti-armour and your armour be anti-infantry.
Also has a real Guard feel to it w/35 bodies and a vehicle
Command squad w/3 Flamers,Surveyor
Chimera w/Multilaser and Heavy Bolter
3 Squads w/Missile Launcher and Plasma Gun
400 points on the nose.
One question,does a surveyor allow a unit's transport to take the free shot as well as the unit?
The list looks pretty good. I'm not a big fan of flamers, but mounted in a Chimera they should do fine. My guess on the surveyor would be no, I think the unit carried and the transport count as separate units, and thus wouldn't be applicable. However that's just my guess, I could certainly be wrong.
