3. SOUNDBITE: (English) Philip Breedlove, 17th Supreme Allied Commander Europe of NATO Allied Command Operations:
"It's less about the exact number, it's more about the fact that there's a great force there that can be exerted if it's required. Inside Ukraine we still see a large number of Russians who are involved primarily in training, advising, assisting and helping the forces of the Russian-backed forces in the East, governments in the East, etc. We don't see combat formations, but we see troops that are there specifically to get backbone, guidance and training to the Russian-backed forces in the East."

5. SOUNDBITE (English) Philip Breedlove, 17th Supreme Allied Commander Europe of NATO Allied Command Operations:
"We agree with the observations of many independent sources to include the OSCE about these movements into the eastern Ukraine. The concern is less about each individual convoy, the real concern is that this international border is completely wide open and maintained open by Russian forces so that forces, supplies, money, fighters can move back and forth at will across this border."

Russia still has enough troops along Ukraine's border to mount a major incursion, NATO's top commander said on Wednesday, and Moscow is using its military might to affect political developments inside Ukraine.
US General Philip Breedlove said a large number of Russian troops were also active inside Ukraine, training and advising separatist rebels.
Moscow has routinely denied it played any direct role in the conflict in Ukraine, which has claimed more than 4,000 lives.
Breedlove spoke during a brief visit to Kiev, where he met with top officials to discuss continued NATO assistance for Ukraine in its fight against Russian-backed separatists in the east.
"We are going to help Ukraine's military to increase its capacities and capabilities through interaction with US - European command," he said.
Ukraine has received multiple pledges of military support from Western nations, but has been frustrated by Washington's reluctance to promise any lethal equipment.
But a senior aide to President Barack Obama said last week that he believes the US should consider giving lethal defensive equipment to Ukraine.
The Ukrainian armed advance against rebel forces ground to a halt and was substantially reversed over the summer as government troops found themselves faced by a well-equipped and determined foe.
"This international border is completely wide open and maintained open by Russian forces, so that forces, supplies, money, fighters can move across at will," Breedlove said.
A truce was agreed in early September but fighting continues daily in several areas of eastern Ukraine.
