http://www.dakkadakka.com/dakkaforum/posts/list/16.page JForum - http://www.jforum.net HH books recently, one Space Marine formation stood out to me as being an interesting addition to 40k, especially if using the forge world heresy era ruleset (I have not read the FW rules yet, so this will be based of "standard" 40k rules). Several books describe legionaries using large ceremite "boarding shields" in a sort of phalanx formation to resist incoming fire and repel assaults. Any points costings are mainly arbitrary to give an example.
The thinking behind this unit (if there is any other than fluff) is to be a unit which has little offensive capability, but can survive a good deal of punishment. The unit however is very slow to move and cannot take advantage of transports easily. Their role therefore is to act as a "screen" for your more vulnerable units, or to sit them on top of objectives.

Boarding Shield: This thick ceremite shield allows marines to receive a much higher degree of protection than his normal power armour, especially from ranged attacks, at the cost of mobility.
Improves armour save by +1 (to a maximum of 2+, included in profile) and confers a 5+ cover save. Models equipped with the shield have the Slow and Purposeful USR (shown in profile) and may not perform sweeping advances. Models equipped with the shield count as bulky for the purposes of boarding transports. Models equipped with the shield cannot gain the +1 to armour save when shot by template weapons.

Shield Wall: Defender squads are famed for their ability to stand steadfast against even the most determined assaults by the most ferocious of foes.
Units declaring an assault against a defender squad never gain the +1 attack bonus for charging. In addition any unit charging the defender squad can never take advantage of USRs or other special rules improving the stats of the unit when it is launching an assault (Furious Charge, Hammer of Wrath, Rage ect). ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/531063/5693018.page http://www.dakkadakka.com/dakkaforum/posts/preList/531063/5693018.page GMT CC. These marines also use hardened armour which give them a re-roll for failed armour saves against blasts. If you want a 40k version check out the IA badab war part 2 were you can use tactical marines with boarding shields that give them re-rolls for armour saves, prevent them from riding in rhinos and razorbacks and only works against ranged attacks for +50 points]]> http://www.dakkadakka.com/dakkaforum/posts/preList/531063/5693210.page http://www.dakkadakka.com/dakkaforum/posts/preList/531063/5693210.page GMT
