"We have a wishlist that we have put before the government of India," Karzai told reporters in New Delhi on Wednesday, adding it was up to the Indian leadership to decide how much help it was willing to extend to Kabul.
India's foreign ministry refused to detail what the "wishlist" contained but local media reports said it included light and heavy artillery, aircraft and small arms and ammunitions.
"The leaders agreed that both countries will work together and will do all within their means to promote stability and security in Afghanistan," said Indian foreign ministry spokesman Syed Akbaruddin.
Karzai's comments came after his office said last week that he would ask for "all kinds of assistance from India in order to strengthen our military and security institutions" during the high-level talks in the Indian capital.
Karzai held closed-door talks late Tuesday with Prime Minister Manmohan Singh after a separate meeting with his Indian counterpart Pranab Mukherjee on his two-day trip which ended on Wednesday.
India has been training a limited number of Afghan military officers for years at its military institutions, but has provided little weapons assistance except for some vehicles.
India's support for Karzai is a reflection of its desire to ensure that nothing would lead to the return of the terrorist Taliban to power in Kabul, analysts say.
In 2011, India and Afghanistan began a "strategic partnership" to deepen security and economic ties.
