In v4.0 of the Swiss
obat is a minor "fault".
Unit 952 Bulldozer (Engineer Tank) is available from 1946 - unfortunately the formation 077 Engineer Tanks only from 1963. It should be changed to 1946 otherwise it's not possible to purchase any engineering tank before 1963.
This is corrected in this attached and REORDERED and NOT Compatble version of the obat053. It also contains a new picture and therefore a new Unit (and some changes with the armored cars as I found out they have their units on the outside and not like apc's inside the vehicle). This Unit 007 GMTF(DURO IIIP) is called "Geschuetzter Mannschafts Transport Wagen" based on the DURO truck. But it's armoured and armed and will be ordered next year an introduced to the troops aprox. 2010.
