adding vehicles question

[xfan51]

now i read in a tutorial that u could add vehicles in a map if u duplicate a weapon in the itmc tag and replace it with a vehicle and clone the chunk in netgame equipment and so on, here is the turorial that i followed

i heard adding tags breaks system link, but if i would just add chunks of pre-existing tags and not duplicate a tag would that break system link??

adding chunks does not break SL to my knowledge, as long as they are proper

nm i got it to do what i wanted, instead of adding vehicles and having to learn the meta fake technique or what ever else that i dont really understand i jus replaced to weapons on the map with vehicles under the scnr tag and it works over system link which is what i was looking for.

umm im new to modding, how come when in entity it doesnt say the names like in the tut it just says reflexive and the meta offsets are different...?
plz help
