3 Commando Brigade

Why? I don't think it really has a negative impact. Although it may be worth limiting its availability in the arsenal to SLs etc only?

If we're going to use it in private Op's, it will be available on the public server too. This is where most people learn how to use and practise with our gear.
We may differ the settings though - perhaps retaining vanilla map markers on the public server, but disallowing their use on private Ops.

I'm not going to try restricting gear on a per-role basis on the public server arsenal. It would require more work than is worth while and players will just share them around / loot anyway.
On private Op's, it's likely that our 3CB units will be updated to automatically carry the relevant cTab equipment based on role, or it can be scripted in to loadouts, so yes, availability can be limited there.

This is exactly my thinking.

Private ops is not the place to practice tasks which are vital for success. 

Picking up on Nick and Robbies points on the mission debrief.

One of the considered benefits of c-tab is that blufor markers are not present on the main map, and only available to command.  This forces more PID'ing of targets and communication, rather than a quick look at the main map.

I don't think it is always helpful to draw comparisons with 15MEU as they have fixed role slots, but Robbie mentioned their use of C-tab.  They're more extreme, only SL and above have the devices.  So their 3 fireteams have no markers at all, and must rely on their SL for info.  We may want to go this route?

Since we're in the experimental phase, I opted to give Androids to both SL and FTLs.  This is something that we can debate, but the intention was that it allows fire teams to act a little more independently, as the SL/FTL can now see their relative positions even when outside of the ShackTac HUD range.

Giving all blufor units the c-tab GPS would overly clutter the map, and is arguable a little too gamey.  Giving everyone Androids again defeats the purpose of realistic info being fed to the sections via their command.

We're in a trial period and it's likely to take some time for us to become comfortable with them.  It does put more pressure on the SL/FTL to keep their sections/teams briefed, which will be a little new to some.

I'd be interested in other peoples opinions, especially non-command elements.

I've already posted some of my arguments in the debrief thread, so I'll simply say that for me it builds the narrative and involvement of the operation. If you're sat providing overwatch/rearguard, being able to glance at the map every now and then and get a vague idea of progress in the current phase is rather comforting for me.

(Related to my comment about regrouping, the mission we did recently with the attempted ambush on the convoy moving along the hillside road: when I got slotted, I trotted back to where we last were and the section had moved on. I could just barely hear some static, but only just faintly - if it hadn't been for map markers, I'd have either been left wandering alone or forced to use sidechat. With an Android, I could have either sent a text to SL/FTL, or checked the tracker.)

From my understanding the Microdagr does not give the units blufor markers, or can be edited so that it does not, I personally really like having the Ctab as a mod as it does add a lot to the game but also think it will only be useful if all units have access to the map in this way rather than just command elements and i think it offers some really good mission opportunities that would not be possible other wise. 

I think its natural to want access to as much in game info as possible, but as people have mentioned, allowing everyone to know where everyone else is at all times will detract from what we do and make us lazy I think. There's no substitute for good comms, and actively PIDing your targets. I'm probably sticking my neck out here, but i think we as a group tend to have a bad habit of coming across a difficult situation in game and try to adjust the scenario to make it easier next time, rather that try to adapt ourselves to overcome it.

This is not to say we shouldn't use C-Tab as personally I think it's a great tool, but the full tab should definitely be restricted to COY/Troop IMO, so that SLs and FTLs don't have access to information that they may feel gives them the ability to act independently.

The Ctab does mainly two things in practice for us

1. Commanding roles like section commanders, fireteam leaders and above and other important roles have access to the tablet or the android. This enables only them to see where everybody else is on the map.

2. "Normal" marines will not see where everybody else is. They can however find their own position with their GPS/MicroDagger.

Especially regarding point two I see the benefit that section members can focus more on their actual tasks. I know it from my own experience that in "downtime" you you take a look at the map and check where everybody else is. That is maybe not terrible but it can lead to situations where you are looking at the map when you should look at your surroundings and listen to what is going on around you.

As mentioney by Nick there are situations where you need to find out where your guys are. In both our private and midweek operations I think this is "fixed" by getting transport to a designated HLS or other drop off point, or you get a teleport. Once you there you can either contact your section via radio, or when you are in a actual transport you can already ask the pilor/driver where you need to go from the HLS  or drop off point to get back to your guys.

Personally from a command point I think SLs and FTLs will be best. Reinforcements should be using radios to regroup. If we need to it might be a good idea to start using map markers to place regroup points on 1-0 (etc) to allow coordination of reinforcements, but giving everyone an android will be chaos on the tracker.

Completely agree with this, 

I was thinking of C-tab being COY/Troop 
android being SL/FTL
Microdagr for everyone else, benefit of this is these can not place map markers.
