. Weâ€™ll find out if and when MRPâ€™s will be used during the OPORD . You can have as many batteries as you need or can carry . It is possible and encouraged but your gear will not be watched so lock it up, the other issue is getting it to you FOB, it may be a hike from the staging area I would encourage you to focus on bringing water, this AO will crush you if youâ€™re not prepared Hydrate or Die literally. . Thereâ€™s a Comms matrix in the BH thread there will be for details in the OPORD from your faction delegating what channel is for what Platoon/squad. Depending on if you get thrown into a squad they may have a specific channel they use. . Everyone there will most likely be running a 5watt radio, unless your running a base station with long range antenna the AO is going to determine you comms usability . Iâ€™ve seen people use that smoke and it should be fine, they just donâ€™t want people using red, as long as itâ€™s cold burning and not home made theyâ€™re fine. . I donâ€™t have a glossary of acronyms but Iâ€™m sure with a quick google search youâ€™ll find it. Not sure what acronym youâ€™re asking about. Hope this helps and remember drink water, bring a case of water and sign up for your faction on Facebook they can help get you answers quickly and even help get you lined up with a squad ahead of time if you ask.
