I've recently started playing 40k, and have about a 2500 pt vanilla Space marine army. heavy on tac squads and rino's. I dont have any Fast yet but plan on deploying with 2 assalt squads one with jetpacks and one without deploying from a land raider. My buddy indicated that you cant combine a Typhoon/Tornado with a Landspeeder Squadron (only 1 per each unit allowed). I cant find anything in the codex or in the 40k rule book stating that they cant be mixed and matched. The sidebar entry for landspeeders indicates they are feildable in units up to 3 and that the typhoon and tornado's are upgrades. So what gives. It would be nice to spend the points and place a tornado in the landspeeder squadron and save the force slot for my assault units. Some one point me in the right direction please.
