Here are just some numbers for everyone.
Germany had 36 Infantry Divisions (around 600,000 men) 2,000 tanks, 3,000 guns, and 2,500 aircraft.
Czechoslovakia had 35 Infantry Divisions, 2,200 guns, 500 tanks, and 880 aircraft. Of these planes, around 450 were bi-plane fighter planes Avia B-534. Which were still quite good in 1938 against first serial Bf 109 B/C/D. Around 250 bi plane attack planes Letov S-328 and around 100 Avia B-71 bombers (licensed SB-2s) rest was a mix of more obsolete planes.
Poland had 30 infantry divisions, 11 cavalry brigades, two motorized brigades, three mountain brigades, 3,000 guns, 700 tanks, and 208-312 fighters, and 60 bombers.
The Czech army at that time was stretching from the Polish border all the way around to the Hungarian border, had the strength of around 42 divisions, manning a massive network of field fortifications that had been in construction since 1935, and while not complete, the existing fortifications combined with the natural defenses of the Sudetenland, acted as a functional defense. Facing them was three armies (North, Center, South) totaling 50 divisions of the German army, that stretched from Moravia to the Hungarian border. While the man power facing each other was relatively equal for the time being, the German outnumbered the Czechs in tanks by five to one, and in aircraft by three and a half to one, however, German tanks while superior in number,were lacking in quality compared to the Czech counter-part in both armor and armament, and many of the men were activated reservists in their forties and older, this, coupled with only having enough fuel for three weeks.
The historic German invasion plans called for the main invasion of Czechoslovakia to happen in the south of Germany. To the north you had three armies, the 4th army with two divisions that held the line around Hermhut and Zittau, to their left was the eight army with four divisions that held the line from Hirschburg to Graz. These two armies were to hold the Czech defends in place. To the left of the 8th army was the fourth army with four infantry divisions and a panzer division. This army held the line from Zegenhals to the Polish border. This army was to break through the strong Czech defenses at Troppau and link up with the 14th army coming from the south towards Olmatz. If the Poles are to fight the Germans, where are they going to get the divisions from?
The Germans had three of the six armies on the attack. The 10th army had 3 infantry divisions, 3 motorized divisions, one panzer division, and one Austrian mountain division. These men were tasked with breaking through the defenses in the Sudetenland and take Prague, The 14th army that stretched from Wien to the March river had the task of breaking through the strong defenses at Brastslava and pushing towards Olmatz. This army numbered some 7 infantry divisions, 1 motorized division, two "field police" divisions, one panzer division and one Austrian mountain division.
