Jump infantry has always been a huge, and I do mean HUGE, part of the Blood Angels. it was a Massive blow that we didn't get the codex space marine vanguard vets. So why play the Archangels demi company with a support choice? Simple. It fits out play style.
Lets begin with what we must take (disclaimer: 1500 to 2000 points is the best way to get this formation detachment on the table). A terminator captain (135 pts) he has a Thunder-Hammer, storm bolter combo, and 2 furioso dreadnaughts (kitted out as you see fit). You can go ahead and put the dreadnaughts in drop pods. or run them say along side a razorback, your choice. what to do about that captain...more on that later. Now to what we may take, any combination of 5 units of terminators, assault termi's, Vanguard, and/or sternguard. lets put our captain in a stock termi squad, either version should work based on your playstyle. Now what about the other 4? well lets go with 2 full 10 man squads of Vanguard (stock loadout) 1 (5 man) squad with power weapons and Storm shields, and lets put a sternguard squad with a heavy bolter turret razorback in the mix for some more shooty support. so that is our core choice. So what does this do for the BA? we get to roll reserves turn 1, reroll failed reserves, AND roll 1 less die for scatter. we make our presence known on turn 1 and then we can benefit from our command benefits on the turn they need to be there.
So lets take a look at the command benefits. We've got the typical reroll on Warlord Traits for the BA codex, The Red Thirst +1 initiative when charging, and zealot once a unit has lost half of its starting number. A lot of people don't like this trait due to it's reliance of loosing models. But there is another way to look at it. All players should know they will loose models. 40k is a wargame, guys WILL BE LOST. Do we like it? Maybe not, but it WILL happen. This trait will make any unit in this detachment be feared. It's about making the opponent choose whether or not to hurt a squad or devote an abnormal amount of firepower to completely wipe a squad (we'll talk more about threat presence in a moment). the thing is to force your opponent to make a choice, to hurt or attempt to kill.
For aux choices I like assault squads (with jump packs now). either on the table OR in a drop pod they can take 4 flamers if you count hand flamers, or 4 meltas if you count inferno pistols, or 4 plasmas if you count plasma pistols. You could even add in an eviscerator and you have a prominent threat at short range.
Lets talk about threat presence depending on what you've taken as your demi-company choices, you can pressure your opponent's back line or run a mobile siege of heavy bolter/assault cannon/[las/plas] (remember our razorback's are fast)/heavy flamer barrage. then your Elite Assault marines drop from the skies. your opponent now asks the questions, or better yet for us knee-jerks, what to shoot at. we hope they choose our main force, allowing our razorbacks/dreads (if placed on foot) to close the distance and catch the opponent by surprise when we assault in turn 2. KAELRICH! you may yell, THEY'RE SITTING DUCKS! Why would you consign your vanguard squads to death!? Because they won't die. They will have help to increase their threat presence. We have 5 HQ choices to play with, which can be Sanguinary Priests (with jump packs). I have won more games on FNP with BA because we Refuse to Leave the field. I prefer to have 4 priests, one without a jump pack with the sternguard squad, 3 with jump packs at with the vanguard vets. so now we have more survivability for our descending angels and an easier choice for the opponent to try and take them out before they can charge (with +1 S,I, and WS).
So what do you think? are you willing to try it?
