Dslyecxi released an updated version of the ShackTac Fireteam HUD on the BI forums.

Quote Dslyecxi :
Once upon a time, we had an idea to make something that would alleviate some of the issues in ArmA with regards to situational awareness. Our ShackTac Fireteam HUD is the solution we came up with, and while it is not completely finalized feature-wise, we think it's more than ready to be used by those who share similar views regarding gameplay's relationship with realism.

The ShackTac Fireteam HUD was designed to do the following:
• Provide situational awareness on where your fireteam members are and what their orientation is. This is intended to represent both peripheral vision, as well as the extended awareness one has in reality. You only see your fireteam members relative to you - no terrain, no other players/units.
• Give you an always-visible way of seeing who your team members are


Changelog:

• Added configs for: Moschnyi, Cicada, Hazar-Kot Valley.
• Markers for units inside vehicles use the vehicle's direction.
• Potential fix for missions that use assignTeam in unit inits.
• HUD compass requires having ItemCompass in your inventory.
• Marker distance ignores height differences.
• Partial A2 compatibility (no support for team colours).
• Fixed a bug where restarting the HUD would recreate an internal local object.

Dslyecxi informed the community on the BI forums an updated version of the ShackTac Fireteam HUD by zx64 has been released.

Changelog:
