With just over 10 thousand active troops posted at bases over 300km from the border - yep

Then you need to swell those figures to the 2 million needed to invade the country, including logistics tail.

Then you need to prep the first echelon up to combat ready stnatus.

Then you need move them to the form up point right on the border, distribute orders, prelim reconnaissance, prelim bombardment, and advance to contact.

... yeah ... could just happen at any point
