Dev squads are great units in my opinion. Their role can change depending on the game, and I think they are very good units. my problem is what to equip them with.
Devs have 5 weapon options. Heavy Bolter, Multi-melta, Missile launcher, lascannon, and plasma cannon. I play blood angles, so these are the only options in my codex. You vanilla players might have additional weapons, but I will focus on these 5.
First it might seem silly to take 5 more guys in your squad, but it is worth it when your
dev squad is under fire and you have to start taking away units you put lots of points into. 10 men also gives you the ability to break up into combat squads if you want to, to split up your fire.
HEAVY BOLTER:
Good anti-infantry weapon. Its
AP is enough to instantly kill 5 of the 8 core units of the non-imperial armies in the game. I would only take them if I put four together in a squad. 12 S5 shots would be frightening to most people. Range is good, price is cheap, and it serves the role well as an anti-infantry weapon. i could go either way on this weapon, so take it if you play horde armies or gun line armies.
MULTI-MELTA:
Good anti tank weapon. Low
AP is good for the extra point on the Damage Table. Not good for anti-infantry unless facing terminators, mega nobz, or other 2+ units. Range is bad at 24'' and melta range will be impossible. If a vehicle is within melta range from your
devs, they are not doing they job correctly. Good weapon but short range makes this weapon a meh in my books.
MISSILE LAUNCHER:
Great weapon. Has lots of range that is very helpful in a
dev squad. Not so helpful in a
tac squad, but essential in
devs. It is a good anti-tank at S8 and a good anti-infantry at S4 AP5. The range of the weapon is very good and that with the relatively low cost makes this a must in a
dev squad.
LASCANNON:
Great waste of points. Not that much better than M Launcher
IMHO. Same range, 1 more strength, 1 more
AP. The extra
AP doesn't matter when going up against tanks, and the extra point of strength is only good that is can cause a penetrating hit to
AV 14. The m launcher has two different fire modes and i don't think that 15 more points is worth it.
PLASMA CANNON:
Good all around weapon. Will kill most infantry in your way, wound on 2's, and no armor saves. OK against vehicles but unless central hole is over the hul,l your out of luck. Gets hot will only kill your marine 5% of the time according to mathhammer, and the good parts about the weapon are very good. I would have to recommend this weapon even though it is slighty pricey.
