Units are minilots (10,000 currency units). Thus, entering BUY TO OPEN 3 EURUSD means "Buy 30,000 Euros using US Dollars." ---

In the C2 Model Account we allow 33:1 leverage, which means you have to "put up collateral" worth 3% of the position. Your account is denominated in US Dollars, so the margin requirement would be 3% of the position, as converted first to dollar value.
