Transport (Xenonauts)

Hi. It does not tell how and what files to alter to increase the capacity of transport in the game. In the middle of the middle of the game 8 soldiers in normal gear it is difficult to resist in the battle against the aliens, with the alien attack, or when you assault the alien base soldier 8 or 10, and terminators (bipedal robot), for example, 17 pieces. In that fight managed to kill 14, but the soldiers have fallen. Is there a possibility to transport make 19 places for infantry or 9 soldiers and 1 technique? Thanks for the reply.
