I usually play in Australia team and i noticed that there's not enough vehicles in their base. There's like 5 Sanchez's, 3 Patriots and 2 Barracks and sometimes there's no vehicles you can use and you have to wait for them to respawn (when server has a lot of players online). So i'm suggesting to add at least 3 more Sanchezes, and a couple more of Patriots and Barracks.
Sorry for bad english if there's some.
Your's sincerely Yydain.
