A very warm welcome to the old git club. I am a younger old git who enjoys the highs and lows of cutting about in ridiculous amounts of kit and taking things like comms with an frustratingly serious dedication at times haha! But..."at the end of the day" the hobby is just a bit of fun and in no way to be taken too seriously. My advice (for what it's worth which is normally approximately zero) is to start as you mean to go on in terms of site etiquette; it is better to over call your hits than under call them out of the uncertainty of being hit. You can never go wrong if you do that, apart from frustrating team mates who may say "that didn't even hit you (expletive)!" lol. Oh well, I'll be back in a minute...(in my head as "dead men can't talk"...) ?
Cheers
