Here is a list i compiled just for fun.
Lots of bodies, lots of vehicles, tons of meltas. Maybe it can even be competitive!
19.LRexecutioner (the plasma one)
the units will embark in chimeras as the following:
chimera a: 1 with 2
chimera b: 5 and 6
chimera c: 7 and 12
chimera d: 15 and 16
there is some optimization to be done (like, you can save 1 melta from chimera b , up to 3 from chim a and c. like, 70 points) but you have a lot of meltas rolling ahead in those chimmies, which can target 2 different enemy units because you have 2 different units shooting from inside, if needed.
Yeah you have bs3 compared to the veterans bs4, but you have much more meltas rolling forward.
4 leman russes can soak up a decent lot of damage to lower pressure from the transports.
the 3 20 men blobs can
-sit on home objective shooting at enemy transports coming in with autocannons, or
-drop the lasguns and autocannons, grab 10 laspistols (2 cc attacks instead of one) and stay on bubblewrap duty
-get assault weapons (GL or flamers) and roll on footslogging
I made this list up in a couple of minutes, but i think that the "quantity over quantity" can be competitive in our Guard... in your face, veterans!
@IronWeevil : please notice that there are no voxes in this list. Kisses
