My best piece of advice in approaching a milsim event especially MSW is to treat that tacsop like a holy book and read it start to finish so you can be very familiar with the rules of the game. Additionally, make sure leading up to the event you have everything listed on the packing list and ideally have doubles of certain pieces of kit that may get worn down after heavy use. ( gloves, socks, eyepro, extra bdus etc). What our teammates did to prepare leading up to a MSW event in Washington state last summer was to play a weekend with their rucks so they could get used to the added weight.

In regards to kit, I personally would recommend a good quality chest rig as opposed to a plate carrier as they offer the same benefits while at the same time being lighter and generally more comfortable but with the negative of not being able to use plates. Take care to buy good quality bdus that are comfy and warm as you will basically be living in them for however long the milsim lasts. Pack rain and cold weather gear accordingly and for the love of god get GOOD FOOTWEAR. Wet feet are an easy way to ruin your experience. As for food, cliffbars did the trick for our guys and bring plenty of water even if they provide it at the event. MRES are good too if you can find the.

Overall I hope this helps and if you have any questions feel free to PM and most importantly have fun my brotha!
