Ukrainian state arms manufacturer Ukroboronprom said on Tuesday it would pay $1 million to anyone who captured a combat-ready Russian military aircraft - an offer it said was open to Russian pilots wanting to switch sides.
The firm will also pay $500,000 for every operational military helicopter seized from Russia, it said in a statement that it asked to be widely shared online.
"To the pilots of the Russian Federation ready to participate in the program, we guarantee the issuance of citizenship of a free country!" it said.
