Yes, I have never used space marines before, so this will be a new experience for me.
I never really saw space marine ships like that before... I just took it for granted that their 6+ armour would make them close to indestructable...... But yes, now i realise..... those lances are going to tear me up. Thanks for the heads up, I know what to do now

I will probably send all 4 SC's in as the vanguard group, and keep my battlebarge and the squadron of Novas together (the lances on the novas should provide adequete cover for my BB's rear, and the BB's cannons and weapons batteries should deter anything coming from the front and sides. The squadron of Gladius' will go ahead with the SC's, and the whole group will try and get behind the enemy, and cause as many criticals as possible, then my battlebarge will finish them.
WRT the Solar Admiral; I got him because it would be a luxury to have Ld 11 with an ordanance heavy fleet like this, especially with my emperor. I will never fail a check

which will gurantee a constant stream of AC. I also dont have any cobras, although I would love some, they dont sell them anymore on the online store =[ Also, what you said about keeping my carriers with my punch line; Is it really wise to keep them in the mayhem of close combat? I rekon the carriers would better serve me off and out of the brawl, where they could remain in relative safety and the Mars could put its Nova Cannon to full use. The emperor could also put its long range guns to use too. The falchions will probably join the punch, because if the punch force is big enough, my opponant will be too disctracted by it, and will hopefully not concerntrait his forces on my carriers. If the opposite happens, ill just race my two carriers in with the punch force, and keep them together.
And, WRT college, Good luck to you man, I get Universities and TAFE down here in Western Australia, so I dont know what college will be like. All i can say is good luck.
