Write a question about the following article: The Romanian army was composed of 92 battalions , 58 cavalry squadrons , 80 artillery batteries of calibers up to 155 mm, two armored trains and some support units. They were positioned along three lines. The first line was manned by the 16th Division in the north and the 18th Division in the south. More powerful units manned the second line: the 2nd Vânători Division in the north, concentrated in and around Nyíregyháza , and the 1st Vânători Division in the south, concentrated in and around Békéscsaba . The third line was manned by Romania's strongest units: the 1st and 6th infantry divisions, the 1st and 2nd cavalry divisions and support units. The third line lay on the railway from Nagykároly , through Nagyvárad  and north of Arad. The 20th and 21st infantry divisions were tasked with maintaining public order behind the third line. The first line was thin, as it was supposed to fight delaying actions until the true intentions of the attacking Hungarian army were revealed. After that, together with troops in the second line, the first line was to be held until troops in the third line could mount a counterattack. The Romanian command planned to use the railways under its control to move troops. The Romanians were highly motivated to fight to unify all the lands of Romanian people into one nation. This had been a goal for quite some time and was supported by Woodrow Wilson's principles of self-determination and nation state. The Romanian soldier was usually a World War I veteran.
How many battalions, cavalry squadrons, and artillery batteries did the Romanian army have?
