Its great to see people are watching my video and discussing it!
The load out I used for each squad was quite varied, this was for fluffy reasons, to keep it fun whilst building each unit and also to give the army redundancy in case some options get better or worse with rules/edition changes.
To answer a few questions, the army is made up of 10x 10 man squads, 1 Capt, 1 Lt, 1 EC, 2 Chaplains and 3 cenobytes.
6x squads are Choppy Squads, they have 1 sword brother, 4 initiates and 5 Neos. I used this ratio (5/5) because these squads will be in the enemies face and will be taking lots of casualties, so its best to have a bit more cannon fodder. The sword brother always gets a power weapon and a combi weapon (melta or plasma). 1 Initiate gets a power weapon and 1 gets a special weapon (normally plasma or melta). I have no preference on which power weapons are used, as long as they are both the same (e.g. 2 x power swords). I like these squads to have a bit of fire power so they can soften up their targets before charging in.
4x Squads are Shooty Squads, they have 1 sword brother, 6-7 initiates and 2-3 neophytes. I have less neos in these squads as they are designed to dig into mid field cover and I want to have more 2+ saves in the unit to make them tougher to get out of cover. I use combi weapon on the sgt (grav or plasma) and have a plasma gun in every squad. I also have a heavy bolter in each unit because often they will be moving so it is best to have more shots to have a better chance of hitting.
For deployment, I run 3 blobs. 2 choppy blobs of 30 marines led by a chaplain and a cenobyte. 1 shooty blob of 40 marines with Captian and Lt.
Hopefully this answers most questions
